Synopsis ## I3C spin-lattice relaxation times ( T I ' S ) of four cyclic hexapeptides of sequence, (X-L-Pro-Y)z, are reported. The TI'S of the protonated carbons, which undergo dipolar relaxation, are interpreted qualitatively in terms of the overall tumbling motion of the molecule and in terms o
A transient nuclear Overhauser effect (NOE) makes measurements of the 13C spin-lattice relaxation times in organic solids complicated. Extended Solomon equations are applied in order to describe 13C spin-lattice relaxation with 'H r.f. field irradiation. Spin-lattice relaxation under r.f. irradiatio
