RESEARCH INTERESTS My research interests include experimental and theoretical studies of different molecules of environmental concern. EXPERIMENTAL INTERESTS Identification of potential disinfection byproducts (DBPs) in drinking water at a high level of confidence by using: Gas Chromatography Fourier Transform Ion Cyclotron Resonance Mass Spectrometry (GC/FT-ICR MS) technique. THEORETICAL AND COMPUTATIONAL INTERESTS Determination of proton affinity of halogenated compounds by using high-accuracy computational thermochemistry PREVIOUS STUDIES HIGHLIGHTS Density functional study of potential energy surface of [CH2N] system Study of Definitive heat of formation of methylenimine, CH2NH, and of methylenimmonium ion, CH2NH2+ by Weizmann-2 theory ( known as new compound methods for high-accuracy computational thermochemistry ) PUBLICATIONS 1.
