Infrared Absorption Spectra: Index for 1945 -1957 contains 16,000 references to published infrared absorption spectra in 33 American and European journals and book.This index aims to provide a means for the location of published absorption spectra from 1945 to 1957, compiling references that consist of an abbreviated symbol of the journal, volume number, and page where an actual spectrum of the compound is reproduced. This book is arranged according to the compounds whose spectra are given, which is roughly similar to that used in Chemical Abstracts.This text is suitable for chemistry students and professionals conducting work on infrared absorption spectra.
