|Title:||Resolved Torsional Splitting in the nu18 and nu19 Bands of Propene|
|Published:||May 08, 2006|
|Abstract:||FT-jet spectra of propene were recorded at 0.005 cm-1 instrumental resolution around 950 cm-1. Thanks to the jet conditions, probably corresponding to Trot close to 80 K, the torsion degrees of freedom are efficiently cooled down and the fine structure of the *18 and *19 vibrational bands could be investigated. The bands are perturbed and approximate variations of the principal rotational constants are obtained, as well as band origins. The A/E torsional splitting appears totally unpredictable over the range of vibrational-torsional energy investigated.|
