Time-resolved dynamics of CH3 roaming in ethanol

ORAL

Abstract

In this talk, we will present a study of ultrafast time-resolved dynamics observed in ethanol using a 9 fs IR pump - IR probe setup in combination with coincident Coulomb Explosion Imaging. This allows us to image the molecular dynamics of an ionized system via a time-dependent measurement of kinetic energy release (KER) of the fragmented ions of ethanol. Direct methyl fragmentation channel in ethanol shows a unique feature in the KER spectrum, which can be attributed to roaming based on previous results from 2-propanol. A comprehensive study using different pump-probe powers will further develop key features of methyl dissociation.
