本文给出了研究具有光滑势的分子薛定谔算子量子传播子的一般约化方案。这种减少是由无限(分别)。指数地)相对于核的质量的平方根倒数的小误差项,取决于C1(resp.分析的)相互作用的平滑度。然后,我们将这一结果的情况下,当一个电子的水平是孤立的,从其余的电子哈密顿量的频谱。
We give a general reduction scheme for the study of the quantum propagator of molecular Schrr odinger operators with smooth potentials. This reduction is made up to innnitely (resp. exponentially) small error terms with respect to the inverse square root of the mass of the nuclei, depending on the C 1 (resp. analytic) smoothness of the interactions. Then we apply this result to the case when an electronic level is isolated from the rest of the spectrum of the electronic Hamiltonian.
