Abstract
It has been found that the aqueous solution of N-nitroso-N-methylaniline when irradiated by 253.7 nm shows photochromism. The unstable photoproduct reconverts to the original compound photochemically as well as thermally. The quantum yields for the forward and backward reaction are respectively 0.23 and 0.58. N-Nitroso-N-ethylaniline also reacts in the similar way. In the alcoholic solutions, different types of reaction occurred; in the absence of oxygen the reaction is mainly the formation of N-methylaniline. It has been suggested that the present photochromism is due to the cis-trans isomerization.
