    Spectra-structure relationships in carbon-13 nuclear magnetic resonance spectroscopy. Results from a large data base (1979)
    Chichester : Wiley-Blackwell
    Organic Magnetic Resonance 12 (1979), S. 289-296

    Notes: A link between a substructure searching system and a 13C NMR data base has been established and permits the retrieval and examination of the chemical shifts associated with specific substructures. The means by which these searches are accomplished is described and the results from the searches are presented and discussed. The system is interactive, and can be used to locate in the data base the chemical shifts of carbon atoms in precisely defined environments. Alternatively, it may be used to learn the range of the chemical shifts possessed by particular types of carbon atoms, such as N-methyl or O-methyl carbons.

    Mass spectra of some isopropyl benzene derivatives. A study of the ortho effect (1975)
    Chichester : Wiley-Blackwell
    Biological Mass Spectrometry 10 (1975), S. 5-17 
    Details

    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy

    Topics: Chemistry and Pharmacology
    Notes: The mass spectra of a series of ortho, meta and para substituted isopropyl benzene derivatives have been determined where the second substituent is —COOH, —C(O)NH2, —C(O)C6H5, —C(Ph)(=NPh) or —CH(Ph)(NHPh). Two bis-isopropylbenzophenones have also been studied. The spectra are characterized by prominent ortho effects which distinguish the ortho derivatives from the meta and para.
