Multinuclear Magnetic Resonance Studies of Phenylphosphonic Dichloride Oriented in Nematic Phases

Abstract

Detailed multinuclear magnetic resonance studies on phenyl-phosphonic dichloride oriented in mixed and individual nematic liquid crystals have been carried out. Analysis of the $^1H,^{13}C$, and $^{31}P$ NMR spectra provided precise geometrical and orientational parameters and the signs and the magnitudes of the indirect spin–spin couplings between heteronuclei
