Intra-trajectory reactions

One of the evidences for the occurrence of intra-trajectory reactions may be an increase of the yields of radiolysis molecular products in the presence of substances in solution that are scavengers of H or OH radicals and suppress Reactions a, b, or c. 

To find the initial yield of water decomposition in a-radiolysis one should know the yields of intra-trajectory reactions and the observed yield of water decomposition.
