The 3 A 2 (nπ \* ) → 1 A 1 X (T 1 → S 0 ) phosphorescence excitation spectrum of jet-cooled xanthione was investigated in the region 14 920-17 600 cm -1 . The structure observed is shown to be due to the T 1 ← S 0 absorption and an assignment in terms of the vibronic structure of that band is propos
The lowest energy vibro-electronic transition, SO-T,, of [l.l.llpropellane is studied by a combination of ab initio molecular orbital and density functional theory methods together with Franck-Condon model calculations. To avoid a possible bias in the simulation of the vibrational envelope, the accu
