Abstract
Isotopic gases could be characterized as multiple gases with the same number of electrons present but with a different number of neutrons within the nuclei. A product collected could contain all possible isotopes of an atom. The separation of these isotopes could be analyzed to better differentiate and understand what is present. Various gases including hydrogen chloride and hydrogen bromide have been synthesized using deuterated sulfuric acid and anhydrous salts in an air-sensitive manner. Once collected, the gases were analyzed through a Fourier-Transform Infrared (FTIR) method. Calculations to determine the rotational and vibrational constants were conducted via PGOPHER as well as least-mean-square regression analysis within Excel. Two peaks were presented in the spectra representing the two different isotopes. For hydrogen chloride these isotopes were for chlorine-35 and chlorine-37. Relationships of the gases present were better analyzed to differentiate the isotopes from one another which can be necessary in chemical synthesis.
