Abstract

The 220-260-nm adsorption system of styrene cooled in a pulsed supersonic expansion exhibits vibrational structure involving 240- and 1600-cm-1 progressions. A distorted excited state is evidenced by an extended progression in the 240-cm-1 mode. Several possible assignments for the two modes are discussed, including ethylene double bond torsion for the low-frequency mode. Implications for styrene cis-trans photoisomerization and the importance of the newly developed supersonic jet direct absorption technique are mentioned.
