Infrared Spectra of Selected Unsaturated Aliphatic Acids and Acid Derivatives.

摘要

A series of unsaturated carbonyl compounds including acids, salts, acid halides and esters have been studied by means of infrared and Raman spectroscopy with the major emphasis on the 700-250 cm to the -1 power infrared region. A number of useful correlation bands have been found for the unsaturated acids and esters. Proposed assignments are presented for acrylic acid, sodium acrylate, methyl acrylate and vinyl acetate. Other spectral features such as hydrogen bonding, resonance, and rotational isomerization are discussed for these molecules.
