甲胺的远红外光谱已经通过傅里叶变换光谱学在340至640 cm-1区域内进行了研究，分辨率为0.006 cm-1或更好。在v = 2 <$0扭转带中有13个子带，v = 3 <$1扭转带中有8个子带，v = 4 <$1扭转带中有1个子带，共得到450个跃迁。根据子带拟合确定了v = 2，3，4扭转状态下的子带参数。在本研究中获得的子水平原点数据的基础上，结合先前的结果，地面和第一激发扭转状态，扭转摇摆问题被认为是。
The far-infrared spectrum of methylamine has been studied by Fourier transform spectroscopy in the region 340 to 640 cm−1with a resolution of 0.006 cm−1or better. About 450 transitions have been assigned to 13 subbands in thev= 2 ← 0 torsional band, 8 in thev= 3 ← 1 band, and 1 in thev= 4 ← 1 band. Sublevel parameters in thev= 2, 3, and 4 torsional states have been determined from subband fittings. On the basis of sublevel origin data obtained in the present study combined with previous results for the ground and the first excited torsional states, the torsional-wagging problem is considered.
