Magnetic susceptibilities of 1,4-dihydro-1,3-diphenyl-1,2,4-benzotriazin-4-yl ( DDB 1 ), 3-tert-butyl-1,4-dihydro-1 -phenyl-1,2,4benzotriazin-4-yl ( BDPB 2) and 1 -(4-chloropbenyl) -1,4-dihydro-3-phenyl-1,2,4-benzotriazin-4-yl ( CDPB 3) radicals have been measured in the temperature range of 4.2-300
ESR, ENDOR and triple resonance studies of 1,4-dihydro-1,3-diphenyl-(la) and 3-tert-butyl-1,4dihydro-lphenyl-l,2,4benzotriazinyl (2a) and of the corresponding radical cation 3a (2a protonated at N-4) yielded the magnitude and the sign of almost all of the 'H and I4N hyperfine coupling (HFC) constant
