The first excited singlet state, an intramofecular charge transfer state, of p-N,N-dimethylaminohenzonitrile (DhWBN) is quenched by tertiary amines. The quenching rate cannot be correlated with the oxidation potential of the amines, but is conrrolled by the size of the amme alkyl group. This unusual
