In this work, we report a study of two thermotropic liquid crystalline samples showing a not common mesophase behavior. The samples, namely a di-benzyloxy biphenyl derivative labelled 9/2 RS/RS, and a bimesogenic liquid crystal labelled L1, show a direct transition between two isotropic phases followed, at lower temperatures, by the optically isotropic, 3D structured, cubic phase. These Cited by: 1. discussion, we will focus on H NMR or proton magnetic resonance. Even though there are many other spectrometers including C-NMR and N-NMR, hydrogen (H-NMR) was the first and is the most common atom used in nuclear magnetic resonance spectroscopy. How does it work? The atomic nucleus is a spinning charged particle, and it generates a magnetic field. Nuclear magnetic resonance is used to measure nuclear magnetic moments, the characteristic magnetic behaviour of specific sciroccowinds.come these values are significantly modified by the immediate chemical environment, however, NMR measurements provide information about the molecular structure of various solids and liquids.. By the early s nuclear magnetic resonance techniques had begun to be. Oct 01, · A borehole is drilled into rock and sedimentary strata into which nuclear magnetic resonance logging equipment is lowered. Nuclear magnetic resonance analysis of these boreholes is used to measure rock porosity, estimate permeability from pore size distribution and identify pore fluids (water, oil and gas).

Bobroff, R.J. Phillips, A. Shekarriz. Nuclear magnetic resonance (NMR) is a method of physical observation in which nuclei in a strong constant magnetic field are perturbed by a weak oscillating magnetic field (in the near field and therefore not involving electromagnetic waves) and respond by producing an electromagnetic signal with a frequency characteristic of the magnetic field at the nucleus. In the past, nematic liquid crystals have been used as orienting solvents in nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR) studies. At first sight, smectic liquid crystals should be even more advantageous in such studies. This impression arises from the belief that their preferred direction would remain fixed *. This edited volume provides an extensive overview of how nuclear magnetic resonance can be an indispensable tool to investigate molecular ordering, phase structure, and dynamics in complex anisotropic phases formed by liquid crystalline materials. The chapters, written by prominent scientists in their field of expertise, provide a state-of-the-art scene of developments in liquid crystal.
