Torsion about the glycosidic linkage in nicotinamide mononucleotide has been investigated by quantitative application of the nuclear Overhauser effect. These measurements show that the syn (chi congruent to 20 degrees) and anti (chi congruent to 200

The spin-labeled cardiolipin 1-(3-sn-phosphatidyl)-3-[1-acyl-2-(16-doxylstearoyl)glycero(3)phosphol]-sn-glycerol has been prepared. The stereoselective synthesis makes use of the monolysocardiolipin 1-(3-sn-phosphatidyl)-3-[1-acyl-2-lyso-sn-glycero(3

13 C solid-phase NMR and pyrolysis-chemical ionization mass spectrometry were used to characterize adsorbed organic material isolated on an XAD-2 macroreticular resin. Pyrolysis-chemical ionization mass spectrometry was used directly to fingerprint t

The deuteron quadrupole coupling constants (QD's) have been determined for a mixture of isomeric monodeuterocyclohexenes (containing a low level of 13C enrichment in the CD bonds) from the 2H NMR spectrum in nematic phase. The measured QD's are: 213.

Measurements of the orientation parameters of a 13C enriched sample of CDH2I in nematic solvent employing 1H, 2H, and 13C NMR are reported. These parameters denoted as SCH, SCD, SHH, and SHD, obey the following relation which assumes mirror plane sym
