Electron spin resonance studies were made of sputtered samples of amorphous Ge1-x14Nx and Ge1-x15Nx. It was found that both the peak-to-peak line width of the broad main electron spin resonance line (a Ge dangling bond) and the g-value for amorphous Ge1-xNx decreased upon increasing r from 0 to about 0.5; where r was the ratio of the N to the total (N + Ar) gas flow rate. It was suggested that these results were not all due to exchange interactions, but could be due to a decrease in anisotropy of the g-value. Satellites of the splitting (of about 116 and 70G) were observed for amorphous Ge1-x14Nx and Ge1-x15Nx, respectively. It was found that the satellites were due to hyperfine interaction with the N nucleus.
