Abstract

The fluorescence and phosphorescence of some aliphatic amines have been measured. A remarkable solvent shift of the fluorescence has been found and explained in terms of the large solvation energy for the Rydberg state. The fluorescence is quenched by oxygen, 1,2-dichloroethane and acetonitrile. A new fluorescence band appears with the addition of water, which has been attributed to the hydrogen-bond complex between the amines and water formed in the former's excited state.
