Photofragment translational spectroscopy of the 1-propyl radical at 248nm
Degradation reactions of alkyl radicals are of interest in combustion chemistry, planetary atmospheres, and the interstellar medium. However, the nature of their reaction pathways is not easily understood as the intermediates are highly reactive. My project will investigate the dissociation dynamics of a simple primary alkyl radical, 1-propyl, upon excitation at 248 nm using a detection scheme known as photofragment translational spectroscopy. Four distinctive product channels are assessed at this wavelength. A preliminary experimental work seems to indicate that the C-C bond cleavage is energetically the most favorable product channel. This observation motivates my research to determine whether the methyl loss channel is the sole and dominant dissociation pathway, and what reaction mechanisms are involved molecularly and electronically.
