Abstract
Product-operator formalism has been extended to weakly coupled I≥1/2 and S≥3/2 nuclear spins to describe the result of nuclear SEDOR (spin echo double resonance) experiments for such spin numbers. By SEDOR modulation, the indirect nuclear spin-spin coupling constant JIS can be measured also when the quadrupolar broadening hides the high resolution evaluation of JIS and the method based on scalar relaxation of the second kind cannot be utilized because of the low quadrupolar relaxation efficiency. Furthermore, the nuclear SEDOR modulation can be performed in low intensity and homogeneity magnetic field. The theory has been applied to estimate JIS of the coupled nuclear spins I=1/2 (F19) and S=9/2 (Nb93) in NbF6- (octahedral symmetry) and of I=1/2 (H1) and S=3/2 (B11) in Na2B1211H11SH (icosahedral symmetry).
