Raman optical activity spectra from density functional perturbation theory and density-functional-theory-based molecular dynamics


Luber, Sandra (2017). Raman optical activity spectra from density functional perturbation theory and density-functional-theory-based molecular dynamics. Journal of Chemical Theory and Computation, 13(3):1254-1262.

Abstract

We describe the calculation of Raman optical activity (ROA) tensors from density functional perturbation theory, which has been implemented into the CP2K software package. Using the mixed Gaussian and plane waves method, ROA spectra are evaluated in the double-harmonic approximation. Moreover, an approach for the calculation of ROA spectra by means of density functional theory-based molecular dynamics is derived and used to obtain an ROA spectrum via time correlation functions, which paves the way for the calculation of ROA spectra taking into account anharmonicities and dynamic effects at ambient conditions.
