Abstract

In this thesis several atmospheric species have been identified and characterised using the matrix isolation technique coupled with FTIR spectroscopy. We have identified the chemical structure of several species produced in the tropospheric layer of the atmosphere, specifically methylene (CH2) radical, Criegee intermediate (CH200), methylthio (CH3S) radical, methanesulfenic acid (CH3SOH), and the dimethyl sulfide-water complex (DMS-H20). Isotopic substitution studies along with quantum chemical computations were conducted to confirm these assignments based on infrared frequencies.
