Abstract
Heterogeneous reaction chemistry involving the nitrogen oxides on particles continues to be vigorously studied in both outdoor and indoor smog chemistry, yet is not often a topic encountered in undergraduate coursework. We report here an upper division physical-atmospheric chemistry laboratory project employing liquid/solid heterogeneous reaction chemistry to generate nitrosyl and nitryl halides, followed by spectral characterization of the product mixtures. High resolution Fourier transform infrared (FTIR) spectroscopy is combined with computational chemistry (Spartan) to identify the nitrosyl and nitryl halides in a mixture of nitrogen-containing gases generated via the reaction of concentrated nitric acid with halide compounds. This discovery-based project introduces high resolution IR spectral assignment, computational methods and atmospheric chemistry to explore the structure and properties of nitrosyl and nitryl halides and their potential roles in both tropospheric smog chemistry and indoor air quality.
