    Description: Interrogar sobre o passado de uma das principais atividades educativas na escolarização inicial de crianças – o ensino de leitura e escrita – é o objetivo central desta obra. Entre as várias contribuições relevantes do livro, uma coletânea de 14 ensaios que abrangem mais de um século, da década de 1870 aos dias atuais, sobressai-se a importância da própria temática para a compreensão da cultura escolar. Os estudos põem em destaque cartilhas, livros de leitura, manuais, textos, artigos publicados em jornais e periódicos, polêmicas em torno dos métodos de ensino e a atuação de quem produziu e problematizou sobre o ensino de leitura e escrita no país. Estão contemplados tanto os interesses econômicos e comerciais subjacentes à produção de materiais para esse ensino quanto as tensões políticas que envolveram as disputas dos educadores, o que permite ao leitor aproximar-se das tematizações, concretizações e normatizações que ao longo do tempo pautaram o debate político e pedagógico sobre a alfabetização no Brasil. O primeiro texto da coletânea trata do método de alfabetização de Thomaz Paulo de Bom Sucesso Galhardo, autor da Cartilha da infância, publicada entre a década de 1880 e o ano de 1992. Seguem-se estudos sobre as experiências de Antonio da Silva Jardim (1860-1891), João Köpke (1852-1926), Ramon Roca Dordal (1854-1938) e Carlos Alberto Gomes Cardim (1875-1938), Arnaldo de Oliveira Barreto (1869-1925), Francisco Vianna (1876-1935), Theodoro de Moraes (1877-1956), Antonio Firmino Proença (1880-1946), Renato Fleury (1895-1980), Lourenço Filho (1897-1970), Antônio D’Ávila (1903-1989), Bárbara V. de Carvalho (1915-2008), Emilia Ferreiro (1935) e João Wanderley Geraldi (1946).

    A theoretical characterization of the quartet states of the SO+ molecular ion (1998)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: The quartet states of the SO+ molecular ion are described theoretically using the internally contracted multireference configuration interaction approach and natural orbitals generated from a state-averaged density matrix. Correlation-consistent polarized-valence quadruple-zeta atomic functions are used in the expansion of the one-electron basis. Potential energy curves are presented for all the states, and solutions of the radial Schrödinger equation allowed the determination of vibrational energy differences and spectroscopic constants. For the b 4Σ− state, this study corroborates the available experimental data and extends the spectroscopic information to regions not yet accessed experimentally; an alternative explanation for the predissociation mechanism is also suggested. For the a 4Π state, our data and analysis are indicative that the vibrational spectroscopic constants derived from the photoelectron spectra might be underestimated. It also leaves open the possibility that the experimental vibrational level numbering might have to be increased by one unit. Transition probabilities as given by the Einstein A coefficients, and Franck–Condon factors are also provided to help analyze the experimental data. Of immediate relevance to the direct ion-fragment spectroscopy, this study predicts the existence of a new bound 4Π state in the energy range of photons used in these experiments. This new state crosses the b 4Σ− curve very close to where it was supposed to be crossed by the 1 4Σ+, and its repulsive side runs almost parallel to this latter state. Our theoretical prediction places the 1 4Σ+ state still lower than it was inferred experimentally. For the a 4Π–1 4Σ+ transition we have also computed the transition moment function and showed that its constancy assumed in the simulation of the experimental intensity data is not valid. © 1998 American Institute of Physics.

    A theoretical study of the electronic structure and spectroscopic properties of the low-lying electronic states of the molecule SiB (1997)

    Notes: Twenty two lowest-lying electronic states of the species SiB are described theoretically using the internally contracted multireference configuration interaction approach and natural orbitals generated from a state-averaged density matrix. Correlated consistent valence quadruple-zeta (cc-pVQZ) atomic functions are used in the expansion of the one-electron basis. Potential energy curves are presented for all the states as well as a description of the electronic structure characterizing the most relevant ones. Dissociation and excitation energies and dipole moment functions complete the electronic structure description. The solution of the radial nuclear equation allowed the determination of vibrational energies and vibrational and rotational constants. For the ground state (X 4Σ−), Re=1.918 Å and De=3.27 eV. The first excited quartet (A 4Π) is located 2.60 eV (Te) higher in energy and has a slightly shorter equilibrium distance (1.811 Å) and a smaller De, 1.00 eV; the transitions X 4Σ−−A 4Π are expected to fall in the visible (green–yellow) region. Higher-lying 4Π states show very noticeable changes in the potential function due to avoided crossings. Within about 1.5 eV from the ground state there are located five doublet states; the lowest one a 2Π, with Te=0.73 eV, Re=1.845 Å, and De=2.54 eV. For selected states, transition dipole moments, transition probabilities, and radiative lifetimes are also presented. Crossings of various states and the energetic closeness of others are expected to play non-negligible perturbative effects in the spectra. The global picture of the electronic states presented will certainly be an important aid to experimentalists in the spectroscopic investigation of this species. © 1997 American Institute of Physics.

    Radiative and predissociative lifetimes of the A 2Σ+ state (v′=0,1) of SH and SD: A highly correlated theoretical investigation (2001)

    Notes: Doublet and quartet states of the HS radical correlating with H(2S)+S(3P,1D,1S) were investigated by ab initio calculations, at the CASSCF-MRCI/aug-cc-pV5Z level of theory. Molecular parameters and spectroscopic constants obtained for both the ground (X 2Π) and the first excited (A 2Σ+) states represent the best overall theoretical description of this system to date. Transition moments, transition probabilities, and radiative and predissociative lifetimes were also determined for the X 2Π–A 2Σ+ system. The values calculated for the radiative lifetimes of the A state show that previous results were too large. Theoretical predissociative lifetimes, although quite sensitive to the region of crossing of the potential energy curves, reproduce the experimental trends. © 2001 American Institute of Physics.

    Notes: A theoretical study at the multireference singles and doubles configuration-interaction level is reported for the six lowest electronic states of BeH+. Of the four new states described, the 1Π and 3Π are bound states supporting at least 8 and 12 vibrational levels, respectively. Two 3Σ+ states are repulsive. For the two known 1Σ+ states improved results are also presented. For all these states, dipole moments and transition moments have been computed. For the bound states, besides the vibrational levels, transition probabilities, radiative lifetimes, vibrationally averaged dipole moments, and a set of spectroscopic constants are also reported.

    Diazasiline (SiNN): Is there a conflict between experiment and theory? (1997)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 106 (1997), S. 151-157

    Notes: The molecule SiNN was investigated with the highly correlated coupled cluster method with single and double excitations and corrections for the connected triples [CCSD(T)], and with the multireference single and double excitations configuration interaction approach (MRCI). A series of basis sets ranging from the simple 6-31G*, 6-311G*, and Dunning's double-zeta (DZ) plus polarization basis sets to the more extended correlated consistent cc-pVTZ and cc-pVQZ ones were employed to check the dependence of the geometry optimization and of the frequency evaluation on the basis sets. Our highest level result of 1859 cm−1 for the harmonic stretching frequency of the NN bond differs considerably from a previous CCSD(T)/DZ prediction of 1726 cm−1. In fact, most of the results analyzed in this study point to a frequency value greater than 1810 cm−1. Reexamining the scant experimental evidence, we estimate the harmonic frequency to be very close to 1830 cm−1. Surprisingly, an extended internally contracted MRCI calculation with the cc-pVTZ basis predicts a frequency 144 cm−1 higher than the corresponding CCSD(T)/cc-pVTZ result. Comparisons with existing density functional studies and with a previous MRCI calculation are also carried out. At the CCSD(T)/cc-pVTZ level, other isomers of SiN2 are further investigated for the first time. One symmetric linear (3∑g−), and one symmetric bent (1A1) structure are found to lie relatively high in energy: 84.60 and 102.23 kcal/mol, respectively, relative to SiNN (3Σ−). However, one cyclic 1A1 and the singlet asymmetric isomer SiNN (1Σ+) are only 6.09 and 15.81 kcal/mol above the global minimum. Although the higher frequencies of the former isomers do not fall in the region of relevance to the experimental assignment discussed in this work, that of the lowest lying 1A1 state (1850 cm−1) is practically identical to the CCSD(T)/cc-pVTZ frequency computed for the 3Σ− state. © 1997 American Institute of Physics.
