The Molecular Geometry of Pyrazine in the Lowest Triplet State from PMDR Spectroscopy

Abstract

The triplet spin sublevel origins of the bands in the phosphorescence of pyrazine in a para-dioxane host are assigned using phosphorescence-microwave double resonance techniques. The assignments cannot be interpreted in terms of a D(2h) structure for the molecule in the triplet state, and indicate a triplet state molecular symmetry of C(2h) or lower.
