Nanosecond Time-Resolved Emission Spectroscopy of 1-Anilino-8-Naphthalene Sulfonate

Abstract

Nanosecond time-resolved emission spectroscopy and fluorescence lifetime measurements are reported for 1-anilino-8-naphthalene sulfonate. Time-dependent spectral shifts are observed that are interpreted in terms of dipole reorientation of the solvent around the electronically excited molecule. Both the radiative and nonradiative transitions probabilities are observed to be strongly solvent dependent.
