spectrum of the Ar–N2O van der Waals complex in the ν3 region of N2O has been recorded by using absorption spectroscopy of a pulsed molecular beam. The band origin is shifted hypsochromically by 0.1509 cm–1 compared to the monomer origin. Rotational constants and centrifugal distortion constants are reported for the ground and first excited vibrational states. Effective structures for the complex in
上述Ar-N的旋转振动解析旋转光谱2 ö范德华在复ν 3 N中的区域2 O具有记录通过使用脉冲分子束的吸收光谱。与单体起始点相比,谱带起始点发生了蓝移0.1509 cm –1的现象。报告了基态和第一激发振动状态的旋转常数和离心变形常数。已经计算出这两种状态下配合物的有效结构,并且在振动激发下几乎观察不到变化。没有证据表明快速振动会发生预分解,并且已确定预分解寿命的下限为10 –9。
