Dr. G. Rattan K. Khalsa is Professor of Chemistry at Thiel College.  At Thiel, she was Assistant Professor from 1980-87, Associate Professor from 1987-92, and Full Professor from 1992 to present.  At Thiel College, she has taught General Chemistry I and II, Chemistry for the Health Sciences, Introduction to Chemistry, CHEMTECH (for non-majors), Inorganic Chemistry, Advanced Inorganic Chemistry, Problems in Chemistry (Undergraduate Research), Advanced Laboratory, Advanced Topics in Inorganic Chemistry, Chemistry Seminar, Honors Interdisciplinary Courses III and IV, Science and Our Global Heritage I and II.

Educational Background

Interests and Experience

Her current research interests include small molecule activation with transition metal complexes, molecular modeling studies of organometallic and bioinorganic complexes, and the separation of metal ions from waste water streams by water-soluble polymer/filtration.

She has worked at Los Alamos National Laboratory (LANL) during sabbatical years 1987, 1993-94, 2001 and during all summers from 1986–1994 (supported on fellowships by Associated Western Universities-U.S. Department of Energy in 1986-7 and 1993-4). She was a Visiting Assistant Professor from 1979-80 at West Virginia University, Morgantown.

Her research projects have included:

(At LANL): Extraction of fluoride and heavy metals from waste water streams by macrocyclic chelators; NMR titration studies (with Dr. Paul H. Smith). Selectivity of diphenyldithiocarbamate in americium(III)-europium(III) separations chemistry (with Dr. Gordon Jarvinen and Dr. Barbara F. Smith). Sonochemistry of high explosives, TNT, DNT, and toxic wastes, PCP's; analysis by mass spectrometry and gas chromatography (with Dr. Nancy Sauer). Small molecule activation by transition metal complexes; characterization of the reaction of CH3C(CH2PPh3)3Pt with dihydrogen; high pressure NMR studies; para-hydrogen induced polarization experiments. NMR kinetics and thermodynamics studies and protonation reactions of M(CO)3(PR3)2(?2-H2) (M = Mo, W); saturation transfer experiments and variable temperature equilibrium studies; synthesis and characterization of novel molecular hydrogen molybdenum and tungsten complexes (with Dr. Gregory J. Kubas).

Dissertation Research with Dr. Theodore L. Brown at the University of Illinois, Urbana- Champaign): Synthesis, NMR kinetics studies and characterization of ligand base adducts of methylcobalamin and methylatocobaloxime

University of Alabama with Dr. Jerry L. Atwood: Synthesis, thermal and X-ray crystallographic studies of organoaluminum complexes.
