✦ Synopsis
Abstract
A new method of generation of N‐acyl‐N‐alkyl nitroxide radicals by photolysis of N‐nitrosoamides is described. ESR parameters are reported for 17 radicals of the general formula RCON(R′)O^.^; the high resolution obtained allows conformational analysis which shows a preferred trans conformation around the CON bond and hindered rotation around the NR′ σ‐bond.
