Abstract

Spectroscopy and vibrational relaxation of 9-hydroxyphenalenone (9-HPLN) and of its 5-methyl derivative are examined and compared. Extensive vibrationally unrelaxed fluorescence is found for the unsubstituted 9-HPLN, which gives some qualitative insight into the pathways of vibrational relaxation in the S₁state. Introduction of the methyl substituent results in at least an order of magnitude increase in the vibrational relaxation rates.
