The Carbon-13 Magnetic Resonance Spectrum of Propane

Abstract

The carbon-13 magnetic resonance spectra of propane and of propane-2,2-d2 are analyzed to give 1j(13C1,H) = 124.35, 1J(13C2,H) = 125.35, 2J(13C1,H) = −4.25, 2J(13C2,H) = −4.39, 3J(13C,H) = 5.80, 3J(H,H) = 7.375, 4j(H,H) < ± 0.18 Hz. The deuterium isotope shift at C2 is 0.72 ± 0.10 p.p.m. to high field.
