Abstract: 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 d9. 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.

Key words: Benzoin, Laser-decomposition, CIDNP effect
