✦ Synopsis

The fluorescence lifetimes and yields of naphthalene vapour have been measured at low pressure as a function of exciting wavelength and of the pressure of added foreign gases. The lifetimes and yields increase with pressure for short wavelength excitation (< 305 nm) and decrease with increasing pressure for excitation > 305 nm. The pressure dependence of the naphthalene S 1 state at low excitation energies is interpreted in terms of collisionally induced vibrational redistribution.
