These atoms are found to be trapped at the substitutional position of the cryo crystal lattice. The ESR line-widths of the N atoms in the recorded spectra appear to be one-fourth as those cites by most authors. It is shown that a calculation is possible which gives a theoretical linewidth matching the experimental one. Two distinct types of matrix surrounding are possible for the substitutional nitrogen atoms, one of which being consistent with the non distorted N{sub 2} crystal lattice. Hydrogen and deuterium ESR linewidths are found to broaden due to the zero point vibration of the atoms. Spin-lattice relaxation times of N,H, and D atoms in solid N{sub 2} matrix are presented.
