二氟甲烷的X-̃-2B1-←-X-̃-1A1光电子能谱受强烈的非谐效应支配,其碎裂通道位置较低。我们使用了与时间无关的无本征态的拉曼波函数方法(RWF)来计算整个光谱。利用我们最近开发的基于残差的算法来计算本征对(RACE),确定了具有最显著Franck-Condon因子的振动跃迁。分析了控制预测带状精度的因素。计算得到的光谱与实验结果非常吻合。
Due to a low-lying fragmentation channel, the X̃2B1 ← X̃1A1 photoelectron spectrum of difluoromethane is dominated by strong anharmonicity effects. We have used a time-independent eigenstate-free Raman wave function approach (RWF) to calculate the entire spectrum. Vibronic transitions with the most significant Franck-Condon factors were determined by employing our recently developed residual-based algorithm for the calculation of eigenpairs (RACE). An analysis of the factors controlling the accuracy of the predicted band shape is provided. The calculated spectrum is in very close agreement with experimental results.
