Abstract : The research involves an extensive investigation of analytical and physical aspects of gas phase spectroscopy. The goal of these studies is the development of high sensitivity, high selectivity, precise, accurate methods of analysis of elements in real samples by atomic adsorption, atomic emission, atomic fluorescence, atomic ionization, and atomic photothermal methods. The major research projects have included: evaluation of the mechanism of vaporization, atomization, excitation, and ionization of N2 molecules in the ICP; derivation of expressions to describe analytical growth curves in AFS; measurement of OH rotational population distributions in combustion flames and evaluation of the departures from thermal equilibrium; evaluation of the analytical uses of flame and furnace coherent forward scatter spectrometry using both lasers and detection methods for atomic fluorescence and atomic ionization. Keywords: Atomic spectroscopy, Analytical chemistry, Gases.
