Proton NMR data for a number of l-.IZ-4-Y-3,5-dimethylbenzenc?s and l-X-2-Y-4-Z-3,5-dimethylbenzenc?s are presented. The proton chemical shifts of the methyl groups at positions 3 and 5 are mainly affected by the ring current effect of the snbstituents. Thii conclusion was strongly supported by the

Studies of line width and chemical shift us. temperature for amide and hydroxyl proton magnetic resonance signals from: barbituric acid, dialuric acid, parabanic acid, alloxan and alloxan monohydrate dissolved in anhydrous dimethyl sulfoxide-d6 are reported. The behavior of the amide signals shows t
Dermorphin (Tyr-DAla-Phe-Gly-Tyr-Prder-NH2), a potent natural peptide opioid, its synthetic L-Ala\* analog, and all the N fragments from the tripeptide (Tyr--DAla-Phe-NH,) to the parent hexapeptide amide were characterized for the first time by means of proton nmr spectroscopy at 11.74 T. Assignmen
