Abstract
C-13-(H-1) nuclear Overhauser effects (n.O.e.) were measured for penicillin G in H-2(6) -DMSO upon selective presaturation of proton resonances and interpreted on the basis of effective correlation times as calculated by analysis of C-13 and H-1 spin-lattice relaxation rates. Preferential occurrence of a compact C2 puckered conformation with folding of the benzoylamino side chain towards the methyl at C2 was given evidence. A Dreiding model of such conformation was built.
