Deuterium magnetic resonance

Further studies on the biosynthesis of ovalicin (57) have demonstrated the use of deuterium magnetic resonance in biosynthetic studies. Compounds (59)—(62), structurally related to (-)-a-santalene (58), have been isolated from the essential oil of Lavandula ojficinalis and L. hybrida " An alternative synthesis of a-santalol...

The thermal dehydration of Cr(0H)3,3H20 to the amorphous hydroxide has been studied.108 X-Ray diffraction data recorded for aqueous solutions of [Cr(H20)6]Cl3 show that the [Cr(H20)6]3+ ions pass relatively undisturbed from the solid into solution.109 A deuterium magnetic resonance study of [Cr(H20)6]3+ has confirmed110 the linear trend of the spin densities at the hydrogen atoms in [M(H20)6]3 + (M = Ti, V, or Cr) ions predicted earlier.

ROBERT remarked that the proton NMR spectra of proteins are extremely difficult to interpret. Recently, however, a natural-abundance deuterium NMR spectrum has been published by Randall in which, of course, each deuteron is showing a single peak. Can one hope, in spite of the low gyromagnetic ratio of the deuteron, that the deuterium magnetic resonance will be a helpful tool in the near future BOVEY agreed that this could be done but the difficulties are great and one would require spectral accumulation times of weeks or months. 

The evidence to support the idea that many, if not all, membrane proteins possess a immobile, long-lived annulus was of two kinds (a) biochemical and (b) spin-label studies. The first was based upon the fact that to maintain full enzyme activity, at least 30 lipid molecules per protein are required. The second was the presence of an immobile ESR signal at high protein to phospholipid content. Tanford has shown however that phospholipid is not essential for full enzymatic activity and that the hydrophobic fluid environment of a detergent is quite sufficient [75]. Furthermore, deuterium magnetic resonance studies on reconstituted ATPase systems have cast... 

Chains in a Phospholipid Bilayer Measured by Deuterium Magnetic Resonance. 

Deuterium magnetic resonance spectroscopy has found wider applications since the advent of highly sensitive Fourier transform spectrometers. Deuterium is preferred choice in molecular and in H NMR spectroscopy in order to provide additional information about proton vibrations and resonances spectra measured before and after deuteration help to locate the exchanging hydrogen atoms.

Two experiments have been performed which allow a comparison between S(q) and for same conditions and the same sample. The form factor is given by SANS and the orientation PjfO) by deuterium magnetic resonance Both are sensitive to deuterated species and can be used in melts for large deuterated fractions.
