Dr. Ted Lorance
Edward D. Lorance, PhD. (VU ’95) is Professor of Chemistry at Vanguard University of Southern California. Dr. Lorance completed his undergraduate education at Vanguard University (then Southern California College) in Costa Mesa, California in chemistry and mathematics before earning his Ph. D. at the University of Arizona in Tucson, AZ (2005); the title of his dissertation was “Synthetic and Computational Studies on Organosulfur Radical Cations and α-Metalated Sulfides” and involved both theoretical and experimental work with radical cations and carbanions. He then completed a two-year postdoctoral fellowship at Arizona State University which involved theory and laser flash photolysis of very fast bond fragmentation reactions. His current research involves the elucidation of reaction mechanisms of radical ion species, excited states, and especially high-temperature, high-pressure aqueous reactions.
In addition to regularly scheduled class and laboratory times, he is available on campus during office hourse (which vary by semester). If questions arise at other times, you may contact him via email or by telephone to make other arrangements by appointment.

2017 SURP Research Projects:
- Extension of the Acidity-Chemical Shift Relationship Discovered in SURP 2016 In SURP 2016, a student researcher discovered a reliable relationship between acidity and chemical shift in various methanesulfonic acid-methanol systems. The relationship needs to be verified with an even stronger acid (trifluoromethanesulfonic acid) and extended to other solvents (DMSO, DMF, THF, ethanol, etc.).
- Exchange Kinetics and Tautomerisms for Equilibrium and Exchange Studies To expand the repertoire of experiments available for PicoSpin NMRs, the exchange kinetics of a series of N,N-dimethylamides will be undertaken with the aim of determining the rotational barrier and correlating it with structure. Also, the tautomerism equilibrium and kinetics of various 1,3-dicarbonyl compounds will be explored by thermal-jump relaxation kinetics with the goal of correlating the rates of tautomerism, the tautomerism enthalpy, and the tautomerism entropy with structure.
- Research-Scale Flow Reactions Suitable for Continuous NMR Monitoring In an effort to expand known applications for the Reaction Monitoring Accessory (Thermo Electron, for PicoSpin NMRs), various flow-reactor kinetics will be investigated, with a focus on reactions catalyzed by Amberlyst 15 (a strongly acidic cation-exchange resin). These reactions include organic standard reactions such as dehydration and acetalization.
