Ultraviolet a n d Visible Absorption Spectra. Index for 1960-1 963.
This volume is the third in the series ‘Ultraviolet and Visible Absorption Spectra.” It provides a four-year supplement Fvitli more than 25,000 references to spectra published during 1960-63. Sixty-six journals and one collection of spectra in book forni are covered. Also included are references t o optical rotatory dispersion and circular dichroism spectra.
This Atlas has been published in collaboration with the Photoelectric Spectometry Group, London, and the Institut fur Spektrochemie und Sngemandte Spektroskopie, Dortmund. Information is given in both English and German. The Atlas consists of a carefully selected collection of solution spectra of compounds containing typical chromophoric groups, supplemented by tables showing the effects of substituents and solvents. Included are sections dealing with biologically important compounds, inorganic systems of interest t o organic chemists, spectrophotometric standards and solrents, in addition t o surveys of chromophoric groups.
