Near Ultraviolet Absorption Spectra of <i>cis</i> and <i>trans</i> Acrolein and Acrolein-<i>d</i>₁

Abstract

The absorption spectrum of acrolein-d 1 (CH 2 =CH∙CDO) has been studied in the region 3900 to 4400 Å with path lengths and pressures up to 10 m atm and temperatures from 25 to 160 °C. This study provides additional information for the interpretation of the vibrational structure observed in the 3 A″– 1 A′ (trans), 1 A″– 1 A′ (cis), and 3 A″– 1 A′ (cis) systems of acrolein, in addition to new information for acrolein-d 1 . Most of the features in these spectra are now assigned.
