Accurate Calculation of Weak Intermolecular Interactions 

Waldrop, Jonathan (2019-07-17)
A variety of weak intermolecular interactions is investigated using both high-accuracy and approximate methods. A high accuracy potential energy curve for the interaction of two krypton atoms was produced as a prerequisite ...

Electronic Structure Calculations of Weak Intermolecular Interactions 

Hemmati, Reza (2021-07-20)
This thesis focuses on a novel the application of Symmetry-Adapted Perturbation Theory (SAPT), Functional-group SAPT (F-SAPT), and F-SAPT difference analysis to chiral self-recognition. In addition to these, a variety ...

Exploring intermolecular interactions through Coupled Cluster, Density Functional, and Multireference Symmetry-Adapted Perturbation Theories 

Smith, Daniel (2015-12-08)
Intermolecular interactions are computed at successively lower levels of theory to establish the relative accuracy of each level. A set of 21 small molecules was first computed using the CCSDT(Q) level of theory to establish ...

QM/MM/MC Simulations for the Elucidation of Ionic Liquid Solvent Effects upon Organic Reactions 

Allen, Caley (2013-04-30)
The research in this dissertation is focused on elucidating and understanding ionic liquid solvent effects on classical organic reactions. Ionic liquids are an exciting class of solvents that have attracted the attention ...
