Abstract

I will present some novel semiclassical methods designed for spectroscopic calculations of high dimensional and/or condensed phase systems. Some of the methods are based on a “divide-and-conquer” approach, where the full dimensional spectra are obtained as a composition of several lower dimensional ones. Others exploit hierarchically the different levels of accuracy of different semiclassical propagators. All methods are within 10-20 wavenumbers Mean Absolute Error average respect to the exact or experiments when available, and are amenable to ab initio molecular dynamics simulations. References 1. F.
