Abstract
The polarisation of phosphorus nuclei (^31^P CIDNP) takes place during the homolytic reactions of dialkyl phosphites. The mechanisms of ^31^P CIDNP and the corresponding chemical reactions are discussed.

## Abstract Chemical polarisation of ^31^P nuclei was discovered and quantitatively measured in the peroxideβphosphite system. The qualitative interpretation of the net polarisation of ^31^P nuclei and of its sign in the products of the radical reactions in the presence of phosphites is given withi
