The steady state and time-resolved spectra of 8-anilinonaphthalene-1-sulphonate under various conditions of solvent polarity, viscosity and temperature have been investigated. Unlike earlier reports, we have actually observed two emissions (Kosower's non-planar (NP) and charge transfer (CT) in all solvents. While in low polarity solvents emission from the NP state is dominant, in high polarity solvents emission occurs mainly from the CT state. In the frozen glass at 77 K the CT emission vanishes. An interconversion of the NP to the CT state starts near the melting point of the solvent.
