The photochemical E-Z isomerisation of the benzophenone-9-anthraldehyde azine (1), benzophenone-9-acridine aldehyde azine (2) and 9-anthraldehyde azine (3) is thermally reversible. The thermal reaction gives the same isomers as the photochemical reaction. We have studied the mechanism of the thermalisomerisation of these azines. Our results are in accordance with an inversion of the N atom which is
