In my research, I am developing methods to predict vibrational spectra of condensed phase systems from ab initio simulations (no empirical parameters or experimental input required). During the last years, my co-workers and me were able to publish the first-ever ab initio prediction of a liquid phase Raman Optical Activity (ROA) spectrum as well as of a liquid phase resonance Raman spectrum, which are both based on novel approaches we have developed.
Are you interested in the algorithms behind computing spectra from molecular dynamics simulations? Some of them are explained in Section V of our recent open access article about the TRAVIS program package. Please have a look:
Tutorial on Computing Spectra
Below, I present a new version of our tutorial on computing vibrational spectra of bulk phase systems with CP2k and TRAVIS. The tutorial gives a step-by-step explanation of how to install the software, decide for a system, and compute the infrared, Raman, VCD, and ROA spectra on the basis of AIMD simulations.
