摘　　要：采用Ｎｄ／ＹＡＧ 激光器的三倍频激光脉冲（３５５ｎｍ） ，研究了安息香的激光光解过程及其ＣＩＤＮＰ 效应，获得了不同动力学参数ｄ９ 下的ＣＩＤＮＰ 谱，由此对预测的反应机理作出了证实．通过自编程序，根据对两种光反应产物不同形成途径的ＣＩＤＮＰ 模拟谱的计算，对安息香光解过程ＣＩＤＮＰ效应芳环上质子的极化情况作出了合理归属．Photo decomposition of benzoin and its derivatives has mainly been investigated from the standpoint as initiators of photo polymerrization. In this article, we obtained different CIDNP spectrum by changing kinetic parameter \%d\%\-9. The photo decomposition scheme of benzoin was verified, suggesting that the benzaldehyde is an escape product and the benzoin is a geminate product. By simulating the CIDNP spectrum, the polarized signals of the arene protons are also distinguished. \;
