Extracting site-specific information about bond rearrangement during ethanol photofragmentation

ORAL

Abstract

Ethanol (CH3CH2OH) has three locations for hydrogen atoms: the hydrogen that is part of the hydroxyl group, the three β-hydrogens attached to the carbon atom opposite the hydroxyl group, and the two α-hydrogens attached to the central carbon atom. When studying bond rearrangement initiated by an ultrafast laser pulse, such as the production of H3+ photofragments, it is desirable to be able to know which sites contribute hydrogen atoms to the final product. Here we describe a technique that combines COLTRIMS data obtained using different isotopologues of ethanol under identical laser pulse conditions (800 nm central wavelength, 3.0×1014 W/cm2 peak intensity, 23 fs FWHM) to extract site-specific data about the formation of H3+ following double-ionization of the parent molecule.
