The focus of this dissertation is to facilitate the computation of the infrared absorption line shape of solid para-hydrogen with an anionic hydrogen atom dopant. For this, we compute the complete potential energy surface for the interaction of H¯ with H2. The coupled cluster with singles, doubles, and perturbative treatment of triple excitations method was used with augmented correlationconsistent polarized valence triple-zeta atom-centered basis sets and a set of bonding functions.
The focus then turns to describing the rovibrational Hamiltonian of the system with the coupledchannel method. We find bound and quasi-bound stationary states of the system for total angular momentum J=0. We also show plots of the wavefunctions of these systems. Using these wavefunctions and dipole moments, we can calculate the line shape of the IR spectrum of H¯/H2.
