Nuclear Magnetic Relaxation

Nuclear Magnetic Relaxation Dispersion in Protein Solutions

Bovine and human B erythrocyte carbonic anhydrases substituted with Co2+ cause an enhancement of the nuclear magnetic relaxation rate of solvent water protons (T1-l) at high pH that is decreased by the addition of carbonic anhydrase inhibitors such as azide and Ethoxzolamide. The part of T1-1 which can be inhibited by Ethoxzolamide is due to exchangeable protons located at the active site of th...

Structural and microscopic relaxation processes in liquid hydrogen fluoride.

The high frequency collective dynamics of liquid hydrogen fluoride is studied by inelastic x-ray scattering on the coexistence curve at T = 239 K. The comparison with existing molecular dynamics simulations shows the existence of two active relaxation processes with characteristic time scales in the subpicosecond range. The observed scenario is very similar to that found in liquid water. This s...

Antimony NQR and Nuclear Magnetic Relaxation

Antimony nuclear quadrupole resonance frequencies in (NH 4 ) 6 Sb 4 (S0 4 ) 3 F 1 2 crystals were measured as a function of temperature, and no evidence of phase transition was detected between 77 K and room temperature. However, the resonance frequencies do not follow the Bayer type exactly. Such an anomaly is attributed to the effect of rotation of ammonium ions which form hydrogen bonds of t...
