Analyses of electron density distributions in earth materials with implications for reactivity.
EMSL Project ID
3273
Abstract
Density functional theory molecular orbital calculations will be used to compute the electron density distributions and their critical point properties of a variety of important silicate minerals and their surfaces to elucidate sites of electrophilic and nucleophilic attack.
