Unlike LNDOR, electron spin echo envelope modulation (ESEEM) spectroscopy enables one to interpret the signal intensity without knowledge of relaxation processes. The technique is put to the test through analysis of the signal from 3gK in the fifth shell around the F-centre in a single crystal of KC

## High -frequency/high-field (95 GHz/3.4 T) electron spin echo envelope modulation (ESEEM) experiments on single crystals and disordered samples of dianisyl-nitroxide (DANO) radicals are reported. At these high microwave frequencies (W-band), the anisotropic g-matrix of the nitroxide radical is r
Electron spin-echo envelope modulations of DPPH in glassy and polycrystalline solids at 100 K have been measured at 4.6 and 9.1 GHz electron spin excitation frequencies. 14N hyperfine and quadrupole coupling parameters have been evaluated through comparison of the experimental data waveforms and the
