ESR in Solid Hydrogen:  Triplet Benzene and Naphthalene

Benzene (C6H6, C6D6, 13C6H6) and naphthalene (C10H8, C10D8) molecules were trapped in solid normal hydrogen, normal deuterium, and for comparison, neon and argon. The triplet states of the aromatic hydrocarbons were excited by steady-state light sources, and their X-band ESR spectra observed. Lifeti...

Description
Summary:Benzene (C6H6, C6D6, 13C6H6) and naphthalene (C10H8, C10D8) molecules were trapped in solid normal hydrogen, normal deuterium, and for comparison, neon and argon. The triplet states of the aromatic hydrocarbons were excited by steady-state light sources, and their X-band ESR spectra observed. Lifetimes in those states were measured. Possible catalysis of the o-H2 to p-H2 conversion by these triplet states is discussed.
