• The magneti chyperfine structure of the J=3, K=2 line in the inversion spectrum of N^14H_3 has been studied by means of a molecular beam maser spectrometer. The results are analyzed by assuming (I・J) type inter-actions of the protons and nitrogen spins, and by taking the coupling scheme of angular momenta F_2=I+J, F=I_N+F_2. The observed hyperfine structure shows two satellite lines on each side of the central line, corresponding to the transitions with ΔF_2=0, ΔF=±1, and ΔF_2=ΔF=±1. From the frequency measurements of these satellite lines the coupling constants of the (I・J) interactions are determined to be -17.67±0.3kc for the protons, and 6.73±0.04kc for the nitrogen nucleus. The theory predicts that the hyperfine components with ΔF_2=0, ΔF=±1 consist of two groups of lines separated by abut 7kc, while the experiments show that the separation is smaller than 4.5±0.5kc. Effects of other types of interactions are taken into consideraction, but they give no appropriate interpretation of the discrepancy.
