The nu4+/-1 + 2nu60 and nu4-/+1 + 2nu6+/-2 perpendicular components and the nu4+/-1 + 2nu6+/-2 parallel component of the CH379Br isotopomer have been found and studied in high resolution (0.006 cm-1). Both perpendicular components are linked altogether and also to the nu2 + nu3 + nu4 band by anharmonic resonances. A model taking these anharmonic resonances and l(2,2) resonances into account has been used. It allowed to obtain a r.m.s. deviation of 0.0065 cm-1 in a least squares fit over 1327 lines (46 being zero-weighted) belonging to the three components of nu4 + 2nu6 and to the calculated KDeltaK = -1 sub-band of nu2 + nu3 + nu4 deduced from the corresponding observed sub-band of nu2 + nu3 + nu4 - nu3.

已在高分辨率（0.006厘米⁻¹）下发现并研究了CH₃₇₉Br同位素异构体的nu4⁺/⁻1 + 2nu6⁰和nu4⁻/⁺1 + 2nu6⁺/⁻2垂直分量以及nu4⁺/⁻1 + 2nu6⁺/⁻2平行分量。两个垂直分量通过非谐共振相互连接，并且还与nu2 + nu3 + nu4带相连。已使用一个考虑了这些非谐共振和l(2,2)共振的模型。在对属于nu4 + 2nu6的三个分量以及从nu2 + nu3 + nu4 - nu3的相应观测子带推导的nu2 + nu3 + nu4的计算KΔK = -1子带的1327条谱线（46条为零权重）进行最小二乘拟合时，得到了0.0065厘米⁻¹的均方根偏差。版权所有1997年学术出版社。版权所有1997年学术出版社
