本文用红外光谱法对O-酰基-α-酮肟R^2C(O)ON=C(R^1)C(O)R^1的光分解机理进行了研究, 并通过对反应物消失和分解产物生成的动力学方程的拟合, 求得了表观动力学速率常数。结果表明, N-O键断裂和Norrish反应在光分解反应中同时存在, 不同的R^1、R^2取代基影响这两种断裂方式的比例。

The title mechanism was studied by IR spectroscopy. Kinetic equations of this photodecompn. were simulated to give the apparent kinetic parameters. N-O bond cleavage and the Norrish-type reaction proceed simultaneously, and the fraction of N-O bond cleavage depends on the substituents.
