✦ Synopsis

An anomalous fluorescence with a quantum yield of 0.017 near BOO0 cm-' is detected from he?rane solutions of aceanthrylene. Excitation and synchronous scan spectra verify that the second acited state with a lifetime of 43 ns is the source of the fluorescence. The absorption spectrum is simulated by PPP SCF CI computations_

Rotationatly resolved fluorescence excitation spectra of two vibronic bands at AE= 410.5 and 414.9 cm -l in the S l ~ S O electronic transition of trans-l-naphthol have been recorded and analyzed. The analysis reveals that the in-plane transition dipole moment of the 410 cm-1 band makes an angle of
