โœฆ Synopsis

A novel pulse technique for the determination of the absolute CIDNP enhancement factor is developed. The photolysis reaction of cyclododecanone is studied with this technique. Anomalous CIDNP enhancement in low magnetic fields is found.

## Magnetic fieid dependence curves are presented for the t3C CIDNP signals resulting from photol>sis of ?-phenqlc~clo-&-ones in cyclohcxane. One of the three biradicakleriwd products, the trapped ketene, reverses its polarization at high field. This is interpreted in terms of a competition betwee
