Nuclear spin relaxation-induced polarization transfer is utilized to investigate the reorientational dynamics of liquid benzene. The second rank reorientational correlation time associated with the overall tumbling of the molecular plane, τ⊥=2.2±0.1 ps, and the motional anisotropy, τ⊥/τ∥=2.4±0.4, were determined at 283 K. From the quantitative measure of relaxation-induced three spin order, the proton shielding anisotropy can be determined, ΔσH[1+(3/5)ηH]=−5.3±1.0 ppm.
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.
