Title:BENZENE'S INFERNO. PART I: A MICROWAVE SPECTROSCOPIC INVESTIGATION
Author(s):McCarthy, Michael C
Contributor(s):Lee, Kelvin
Subject(s):Rotational structure/frequencies
Abstract:Benzene is of central importance in combustion chemistry because formation of the first aromatic ring is the rate-limiting step in polycyclic aromatic hydrocarbon (PAH) growth. For these reasons, the fragmentation and isomerization of benzene are highly topical, as are intermediates formed in route to larger rings. Using a combination of broadband and cavity Fourier-transform microwave spectroscopies and newly developed analysis and assignment tools, the discharge products of benzene have been extensively studied in the 2-19\,GHz frequency range. In addition to rotational transitions from 30 known species, evidence has been found for eight entirely new hydrocarbon molecules; these species include both branched and chain fragments of benzene, high energy isomers, and larger molecules such as phenyldiacetylene and isomers of fulvenallene; together they account for nearly 1/3 of the observed transitions, and about 1/2 of the spectral intensity. Benzene fragmentation and isomerization, as well pathways that may lead to larger aromatic rings will be discussed in the context of the newly discovered molecules.
