The new methodology explored in Rmat3 can be extended in the future to treat larger molecular systems as well as photodissociation and photoassociation, charge exchange and predissociation.
Some areas explored include photofragment spectroscopy and predissociation dynamics of weakly bound molecules, de-wetting and hydrophobic interactions in physical and biological systems, intrinsic particle properties from vibrational spectra of aerosols, and nanofabrication of plasmonic structures.
