The proton dipolar spin-lattice relaxation time T 1D was measured at several Larmor frequencies in the various smectic phases of the liquid crystal terephthal-bis-butylaniline (TBBA) as a function of temperature and orientation of the sample in an ex

The deuteron fast Fourier transform (FFT) spectra of the ring deuterated nematogens para‐azoxyanisole (PAA‐d8) and p‐methoxybenzylidene p‐n‐butylaniline (MBBA‐d8) have been studied as a function of temperature. An interpretation of the sp

Proton spin–lattice relaxation times (T1) have been measured in methyl deuterated para‐azoxyanisole (PAA‐d6) and in ring deuterated para‐azoxyanisole (PAA‐d8) samples as functions of frequency and temperature. When compared with recent orde

The proton spin dipolar relaxation times and dipolar echo responses were studied for the nematic phase of ring-deuterated p-methoxybenzylidene-p-n-butylaniline (MBBA-d) as a function of temperature and frequency. Measurements of the proton dipolar ec

Nitrogen-14 resonance lineshapes in the isotropic phase of a nematic (p-azoxyanisole) and of a smetctic-A (dietylaxoxybenzoate) liquid crystals have been studied using fast Fourier transform techniques. The temperature variation in linewidth is difer

Proton spin–lattice relaxation has been studied in the nematic phase of MBBA and MBBA-d8 samples. The proton T1 temperature dependence appears to come from the motions of side chains as in p-azoxyanisole. Order of magnitude calculations of T1 based

Proton and deuteron Fourier transform magnetic resonance spectra are reported for a variety of nematic liquid crystals. We discuss the widening of the dipolar splittings of phenylene protons due to terminal proton groups, which results in the incorre
