We present a complete calculation of the dynamical polarizability induced on an atom or a centrosymmetric molecule by the presence of a perfect metallic surface. This polarizability, which appears as a direct consequence of modifications by the surface of vacuum fluctuations is here calculated by us
A new method is provided for the calculation of Raman intensities. Atomic polarizabilities are used as parameters to reproduce the experimental intensities. The method was applied to an signal crystal. It is shown that the MgF 2 use of anisotropic atomic polarizabilities allows the simulation of bot
An efficient procedure is presented for calculating analytic gradients in the framework of a semiempirical multireference configuration interaction method. The same algorithm is used to locate the lowest energy point of a conical intersection by the direct method of Bearpark et al. (Chem Phys Lett 1
