分子在高振动态上的局域模振动 总被引:3,自引:0,他引:3
本文讨论多原子分子出现局域模(local mode)振动的条件并说明局域模振动是分子伸缩振动在高振动能区中的普遍趋势。 相似文献

用Fourier变换光谱仪和特制的多次反射吸收池在0.01cm~(-1)分辨率上记录了硅烷的(3000),(4000)和(5000)伸缩振动泛频带的光谱.这些光谱显示出了清晰的对称陀螺转动结构,它们正是理论预言的球陀螺分子在局域模极限时的行为,从而为详细研究分子的局域模的转动结构提供了首次极好的机会.文中并用局域模和简正模两种图象对这些谱带做出了解释和分析,讨论了在分子中单键激发后的动力学过程. 相似文献

采用Morse根于描述C_2D_2分子中C-D键的伸缩振动,用谐振子描述C-C键伸缩振动,更新构造了C2D2分子的振动哈密顿,自行设计了非线性最小二乘拟合程序,并用它对C2D2分子的伸缩振动能级进行拟合,得到了基本的势能参数.理论计算与实验结果符合得很好,拟会的标准差为1.14cm-1;利用这些参数进一步计算了C2H2和C2D2的振动能级. 相似文献

The absorption spectrum of HD16 O was recorded at a resolution of 0.02 cm-1 with a Bruker IFS 120HR Fourier Transform Spectrometer in the region of 9600-10200 cm-1. As far as we know it is the first time to record and analyze the HDO spectrum in this region which was assigned as the ν1+2ν3 and 2ν2+2ν3 bands. With the strong resonance interactions between these two bands considered, the spectroscopic parameters were optimized by the nonlinear least squares method. 相似文献

The Fourier transform spectrum of the ν2+2ν3 band of the HDO molecule was recorded with a resolution of 0.02 cm-1. The spectrum was rotational analysed and the spectroscopic parameters of the (0,1,2) state were estimated in terms of Watson's effective rotational Hamiltonian model and also the model in the Padé-Borel approximation form. They reproduce the upper energy levels with an accuracy close to the experimental uncertainty of 0.001 cm-1. 相似文献
