    Spin-coupled VB theory of molecular electronic structure. Ground and low-lying 1Σ+ states of CH+ (1985)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: The spin-coupled VB theory is applied to the ground and low-lying 1Σ+ states of CH+. Using 500 spin-coupled structures, the calculated values of the spectrosopic constants for the ground states De(eV)=4.14 (4.26), ωe(cm−1)=2845 (2858), Re(A(ring)) =1.135 (1.131); experimental results are given in parentheses. The form of the ground state potential energy curve is very close to the MCSCF-CI curve of Green et al. [Phys. Rev. A 5, 1614 (1972)], and similarly the excited states are very similar to those obtaind by MCSCF-CI methods by Saxon et al. [J. Chem. Phys. 73, 1873 (1980)]. The only exception is in the 4 1Σ+ state below R=3.5a0 where there is an avoided intersection with a Rydberg state. At least for small systems of this kind, the spin-coupled VB approach is capable of the same level of accuracy as the best MCSCF-CI methods, but uses an order of magnitude fewer functions. Each state in the spin-coupled VB calculation is dominated by one or two structures. This provides the wave function with much visuality, but without the usual attendant loss in accuracy.

    Notes: [Auszug] PROF. H. B. BAKER has shown that prolonged contact between benzene and phosphorus pentoxide results in a marked rise in the boiling-point of the liquid. From this we may safely infer that corresponding and concurrent variations in other physical properties, such as the refractivity, ...

    Notes: [Auszug] IT is known that under some conditions not clearly defined or understood, mercury and helium may become so intimately associated that the separation of the one from the other is difficult. According to prevalent views, helium is a highly inert gas, and is therefore incapable of combining with ...

In a second note (NATURE, March 7, 1925) the empirical formula of the compound was given as HgHe, and afterwards (NATURE, June 20, 1925, p. 947) the formula HgHe10 was substituted for the ...

    Notes: [Auszug] IN a former note (NATURE, March 7, p. 337), I stated that a quantitative analysis of mercury helide showed that 210.79 parts by weight of mercury combined with 4.18 parts by weight of helium. I have to regret that this is incorrect. In checking the calculations before incorporating the results ...

    On the nature of β-galactosidase synthesized by the DNA-directed cell-free system (1973)

    Notes: Summary The β-galactosidase product of the DNA-directed cell-free system for the synthesis of protein of the lac operon, developed by Zubay and his colleagues, has been purified to radioactive homogeneity and compared to wild-type β-galactosidase. When analyzed by sucrose gradient centrifugation, SDS-gel electrophoresis, and kinetic analysis, the purified cell-free enzyme behaves identically to the purified wild-type β-galactosidase.
