| Abstract: | Investigation of the Selective N.M.R. Spin Echo Response of I = 1 Systems in Solids Demonstrated on Potassium Oxalate Monohydrate The theory of the nonselective spin echo response in solids for dipolar-coupled spins I = 1 with quadrupole interaction by BODEN et al. 5] is modified for the case of selective irradiation to only one line of the n.m.r. spectrum. The theoretical results are compared with 1H-n.m.r. experiments on dipolar-coupled protonpairs of a (KCOO)2 · H2O single crystal. This is possible because in this material the interpair dipolar interaction is substantially smaller than the intrapair dipolar interaction. An echo response results which has some similarities to the behaviour of spin systems with heteronuclear coupling. |
