摘要：

The far-infrared laser magnetic resonance spectra associated with both fine-structure transitions in N-14+ in its ground 3P state have been recorded. This is the first laboratory observation of the J = 1 <-- 0 transition and its frequency has been determined two orders of magnitude more accurately than previously. The remeasurement of the J = 2 <-- 1 spectrum revealed a small error in the previous laboratory measurements. The fine-structure splittings (free of hyperfine interactions) determined in this work are DELTAE10 = 1461.13190 (61) GHZ DELTAE21 = 2459.38006 (37) GHZ. Zero-field transition frequencies which include the effects of hyperfine structure have also been calculated. Refined values for the hyperfine constants and the g(J) factors have been obtained.
