The resonance enhanced multiphoton ionization (REMPI) of Si (CH3)4–nCln compounds (with n = 0, 1, 2, 3, 4) was measured in the 400–360 nm range. The resonances observed were attributed to a
silicon atom formed in the 1D2 excited state. This indicates that the first step in the photochemical process
is the dissociation of the molecule which is followed by the ionization of the silicon atom.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
