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

✦ Synopsis
Vibrational analysis of the absorption spectrum of triphenylene-h,, in Shpolskii matrices, supplemented by calculation of excited-state vibrations performed within the Warshel-Karplus formalism, has resulted in an Improved set of vibrations active in the S, + S,, transition. Experimental evidence and calculation of electronic transitions point to the location of the S, state at = 32000 cm-'.
