Abstract

O($^{1}$D) insertion reactions with methylamine are a predicted pathway to form aminomethanol\footnote{B. M. Hays, S. L. Widicus Weaver, J. Phys. Chem. A, 117, 32, 7142-7148 (2013)}$^{,}$\footnote{M. E. Wolf, P. R. Hoobler, J. M. Turney, H. F. Schaefer III, Phys. Chem. Chem. Phys., 2019,21, 24194-24205}, a possible glycine precursor in the interstellar medium. In a preliminary study, O($^{1}$D) insertion into methane and ethylene have shown to successfully result in the formation and spectral detection of methanol and vinyl alcohol, respectively\footnote{B. M. Hays, N. Wehres, B. Alligood DePrince, A. A.M. Roy, J. C. Laas, S. L. Widicus Weaver, Chem. Phys. Lett., 630, 18 (2015)}. Despite the detection of these insertion products, the complex mixture resulting under these conditions has not been well characterized. Likewise, O($^{1}$D) insertion reactions with methylamine have proven more troublesome. We have examined the reaction pathways of the chemical mixtures resulting from the 248 nm laser photolysis of ozone + methane and ozone + methylamine. Millimeter/submillimeter spectra have been collected in both the frequency and time domain. The observed product pathways have been modeled using F0AM (Framework for 0-D Atmospheric Modelling) with the aim of determining the ideal experimental conditions to extend the lifetime of aminomethanol to enable its spectral detection. The results of both the laboratory studies and the modeling work will be presented.
