Correlation of deuterium quadrupolar couplings and carbon-13 chemical shifts in ordered media by multiple-quantum NMR

Article Abstract:

An experiment to measure and assign the 2H quadrupolar couplings in ordered medium with a heteronuclear multiple quantum spectroscopy is discussed.

Molecular characterization of hexaoctyloxy-rufigallol in the solid and columnar phases: a local field NMR study

Article Abstract:

An investigation is made on the 1,2,3,5,6,7-hexaoctyloxy-rufigallol by using the two-dimensional nuclear magnetic resonance technique. The analysis of the dipolar couplings shows that the three-noneqivalent aliphatic chains in RufH80 exhibit vastly different structural and dynamical characteristics.

Usage, Nuclear magnetic resonance, Structural dynamics, Spin coupling

Deuterium isotope effect on volume phase transition of polymer gel: temperature dependence

Article Abstract:

Several samples at varying concentrations of poly(N-isopropylacrylamide) gel(PNIPAM) and the phase separation of linear PNIPAM solution were examined to find the deuterium isotope effects on the volume phase transition of the gels.
