    Notes: A survey of members of the U.K. QSAR Discussion Group has been made to determine the extent of use and development of chemometric and artificial intelligence (AI) methods in the analysis of multivariate quantitative structure-activity relationship (QSAR) data in the U.K. Chemometric methods were found to be well established in both industrial and educational establishments and there was significant method development occurring. AI methods were not employed to any great extent and the general level of interest in these techniques was low compared to chemometric methods. A requirement for more education in multivariate statistical methods and regression methods was indicated. A need for a user-friendly, comprehensive, commercially available multivariate statistical package containing multivariate stability testing and regression diagnostic methods was identified.

    A robust PLS procedure (1992)
    New York, NY : Wiley-Blackwell
    Journal of Chemometrics 6 (1992), S. 189-198 
    Details
    ISSN: 0886-9383
    Keywords: Robust regression ; Partial least squares ; QSAR ; Perturbation study ; Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: A robust partial least squares (PLS) regression algorithm is developed. This is achieved by substitution of the univariate regression steps in the iterative PLS2 algorithm by a robust alternative. The angle between loading vectors from both perturbed and unperturbed solutions is used as a measure of robustness. By means of a perturbation study on a structure-activity data set, it is demonstrated that the stability of the robust method is superior to standard PLS.

    Notes: A new time-of-flight mass analyser compatible with conventional continuous ionization methods is described. A mass resolution at m/z 2000 of m/Δm〉2000 (50% valley) is predicted for the instrument which is presently being prototyped. Sensitivity advantages over scanning instruments are also predicted for this instrument.

    The elimination of carbon monoxide from molecular ions of phenol and other [C6H6O]+· isomers (1982)
    Chichester : Wiley-Blackwell
    Biological Mass Spectrometry 17 (1982), S. 81-85 
    Details
    ISSN: 0030-493X
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: Phenol and five acyclic isomeric compounds have been investigated using electron impact and field ionization techniques, mass analysed ion kinetic energy spectrometry and collision induced dissociation mass analysed ion kinetic energy spectrometry. The kinetic energy release data corresponding to the elimination of carbon monoxide from the molecular ions show that at least two structures of the reactant ion are involved. The electron impact and field ionization collision induced dissociation mass analysed ion kinetic energy spectra indicate that under electron impact conditions, the phenol ion partially isomerizes to another ion structure. An isomerization of about 40% to the structure of cis-2-hexen-4-yn-1-al is in good accordance with the spectral data.

    Notes: Tristrifluoromethyl antimony dichloride, (CF3)3SbCl2, reacts with water to give mono- and dihydrates. A solution of tristrifluoromethyl antimonic acid H(CF3)3Sb(OH)3 may also be isolated. It is a strong monobasic acid which is fairly stable to alkaline hydrolysis. The pyridinium salt has been isolated and with hydrochloric and hydrobromic acids gives derivatives of the type C5H5NH(CF3)3SbX3 (X = Cl, Br).

    The mass spectra of some alkyl and aryl oxazoles (1968)
    Chichester : Wiley-Blackwell
    Biological Mass Spectrometry 1 (1968), S. 13-29 
    Details
    ISSN: 0030-493X
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: The mass spectra of a variety of alkyl and aryl oxazoles have been determined and the spectra analyzed with the aid of deuterium labelling and high resolution mass spectrometry. In contrast to the corresponding benzenoid compounds, the mass spectra of isomeric alkyl oxazoles are distinctive and in this respect are akin to those of the corresponding pyridines. Further analogy to the pyridines is suggested by the unfavorable nature of a carbonium ion adjacent to the 2-position and this effect may be used to locate alkyl substituents attached to the oxazole nucleus. The loss of carbon monoxide from the molecular ions of 2,5-disubstituted oxazoles probably occurs with ring opening and migration of the C-5 substituent (e.g.Br) to the C-4 position.

    Electron-impact studies - LI:For Part L, see Ref. 4. Hydrogen randomization in the stilbene molecular ion (1969)
    Chichester : Wiley-Blackwell

    Notes: Hydrozen randomization precedes the formation of M+· — H· and M+· — CH3· species from the stilbene molecular ion at 15 eV. The carbon atom involved in the M+· — CH3· elimination originates randomly from the whole molecule. The [M — 15] ion (m/e 165) in the spectra of stilbene and 9,10-dihydrophenanthrene is produced from a common ion.
