摘要: The less known properties of cross relaxation between detectable spins I and fast relaxing S, such as the two types H1 dispersion occurrence minima rotating frame Zeeman time T1x(I), when γH1T1(S)min<1, or dipolar T1d(I), γHL, eff(I) T1(S)min<1 T1(S)min≪T2(IS), are briefly discussed in framework Blinc–Pirs–Žumer theory. experimental results on (protons deuterons) S (bromine, iodine, chlorine) cubic phases solid NH4Br, NH4I, NH4Cl, their deuterated analogs, presented explained.
