NATURE OF THE EXCITED STATES OF 2-NAPHTHOL AND 1-ANTHROL HYDROGEN BONDED WITH PYRIDINE

Abstract
The transient absorption spectra were observed for 2-naphthol and 1-anthrol in pyridine upon sensitization by suitable triplet energy donors. No transient was produced by direct excitation. The intersystem crossing process is not the deactivation pathway of the singlet excited species hydrogen bonded with pyridine.
