Vibrational Structure of a High-Resolution UV Absorption Spectrum of Methyl Vinyl Ketone in the Gas Phase

Abstract

The resolved vibrational structure of a UV absorption spectrum of the molecule in the gas phase is obtained. The (0–0) bands of the isomers are found. The fundamental vibrational frequencies and (0–v) torsional vibration transitions for the s-trans and s-cis isomers of the molecule are found in the ground (S₀) and excited (S₁) electronic states. The 68 absorption bands are assigned completely.
