Abstract:

The EPR spectra attributable to N2- trapped in KCl, KBr, and KI have been observed between 2 and 20K. The N2- impurity occupies a negative-ion vacancy and is oriented so that the equilibrium direction of the N-N bond is a 100 direction of the crystal. The principal g factors of N2- are characteristic of a doublet Pi12 ground state, and the nodal plane of the pi orbital is a 100 plane of the crystal. In KI, N2- appears to be undergoing a libratory motion, which is, however, confined to this 100 plane. The 14N hyperfine structure, which is perfectly resolved in KClN2-, is used to determine atomic parameters. Author
