分子光谱学代数模型的比较

A comparison between algebraic models of molecular spectroscopy

R. Bijker, A. Frank, R. Lemus, J. M. Arias, F. Perez-Bernal

摘要:

我们讨论了一个适用于分子光谱学的代数(或振动子)模型。该模型是制定在分子点群下的张量算子。通过这种方式,我们已经确定了在以前版本的振子模型中不存在的相互作用,其中哈密顿量用Casimir算子及其乘积表示。包含这些新的相互作用导致可靠的光谱预测。作为一个例子,我们研究了甲烷分子的振动激发,并将我们的结果与其他代数模型中得到的结果进行了比较。

英文摘要:

We discuss a symmetry-adapted algebraic (or vibron) model for molecular spectroscopy. The model is formulated in terms of tensor operators under the molecular point group. In this way, we have identified interactions that are absent in previous versions of the vibron model, in which the Hamiltonian is expressed in terms of Casimir operators and their products. The inclusion of these new interactions leads to reliable spectroscopic predictions. As an example we study the vibrational excitations of the methane molecule, and compare our results with those obtained in other algebraic models.
