An ESR study of @radiated sin\_rle c.rystals of cyanoacotyl hydrazide indicates that the free radical formed is the corresponding hydrazyl (NCCH,CONNH,), in which a large fraction of UIC unpaired spin density is located on the a-nitiogcn atom. Stable triaryl substituted hydrazyl free radicals R, -N
The ESR spectrum of the tricyclohexylmethyl radical was obtained from tricyclohexylmethyl chloride and was studied in solution in the range 275-455 K. It has a half-life of about 30 min at room temperature. The complex hyperfioe structure of the radical was analysed with the help of MNDOWHF calculat
