Computational Vibrational Spectroscopy

Abstract

Vibrational spectroscopy is a powerful technique to characterize the near-equilibrium dynamics of molecules in the gas-and the condensed-phase. This contribution summarizes efforts from computer-based methods to gain insight into the relationship between structure and spectroscopic response. Methods for this purpose include physics-based empirical energy functions, machine-learned force fields, and methods that separate sampling conformational space and determining the data for spectral analysis such as map-based approaches.
