✦ Synopsis

The electronic absorption and fluorescence spectra of the cation derived from 9-aminoanthracene (9-anthrylamine), in water, are anomalous by comparison with those of the 1-and 2-anthrylammonium ions. The similarities of the spectra of the cation of 9-anthrylamine with those of anthrone and its cation lead to the conclusion that the former cation is not the 9-anthrylammoniurn ion but rather its tautomer, the protonated imine analogous to anthrone. In ethanol and in the solid state, meaSUI'dbk quantities 0 1 both the protonated imine and 9-anthrylammonium ions exist.
