1The (1) H NMR spectrum of pyrazole in a nematic phase.

Provasi P1, Jimeno ML2, Alkorta I3, Reviriego F3, Elguero J3, Jokisaari J4.

Magn Reson Chem. 2016 Aug;54(8):637-40. doi: 10.1002/mrc.4422. Epub 2016 Mar 6.

The experimental (1) H nuclear magnetic resonance (NMR) spectrum of 1H-pyrazole was recorded in thermotropic nematic liquid crystal N-(p-ethoxybenzylidene)-p-butylaniline (EBBA) within the temperature range of 299-308‚ÄČK. Two of three observable dipolar DHH -couplings appeared to be equal at each temperature because of fast prototropic tautomerism. Analysis of the Saupe orientational order parameters using fixed geometry determined by computations and experimental dipolar couplings results in a situation in which the molecular orientation relative to the magnetic field (and the liquid crystal director) can be described exceptionally by a single parameter.
