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.
