The Interpretation of the Infrared Spectra of Conjugated Polyenes in the 1000900 cm1 Region

Volume 25, Number 3 (June 1971) Page 368-371

Colthup, N.B.

The ir spectra of conjugated polyenes such as fatty acids and derivatives are known to have band patterns in the 1000-900 cm−1 region which are characteristic for various arrangements of cis and trans groups within the different polyenes. This paper presents an interpretation of these bands and also predicts absorption patterns for less commonly observed polyenes with cis or trans groups.
