The temperature behavior of the electron spin resonance (ESR) spectra of nitrogen donors in n-type bulk 3C SiC monocrystals with (N-D N-A) approximate to 10(17) cm(-3) was studied at T = 10-50 K. The triplet lines due to the hyperfine (hf) interaction with N-14 nuclei (I = 1, 99.6%) along with a single line with similar isotropic g values of 2.0050(3) were observed in the ESR spectrum of n-type 3C SiC monocrystals in the temperature interval from 10 to 35 K. The observed reduction of the hf splitting for the nitrogen donor residing cubic position (N-k) in the temperature interval from 15 to 35K was attributed to the motion narrowing effect of the hf splitting.
