The infrared spectra of gaseous and solid N-bromo-hexafluoro-2-propanimine, (CF3)2CNBr, have been obtained from 2000 to 50 cm−1. The vibrational assignment for the normal modes is proposed based on infrared band contours, group frequencies and normal coordinate calculations utilizing Cs symmetry. The structural parameters have been obtained from ab initio MP2(full)/6-311 + G(d,p) calculations employing
从2000到50cm -1获得了气态和固态的N-溴-六氟-2-丙胺(CF 3)2 C NBr的红外光谱。基于红外波段轮廓,群频率和利用C s对称性的法向坐标计算,提出了法向模式的振动分配。结构参数是使用Gaussian-03程序从头算MP2(完整)/ 6-311 + G(d,p)获得的。此外,已经使用MP2(full)/ 6-31G(d)计算了正常模式的频率和势能分布。将所有这些结果与一些相似分子的相应数据进行比较。
