Abstract
Triple-rhodium quantum effects in the HMQC spectra of [Rh-6(CO)(15)L][L = M eCN, I, PBu3n, P(OPh)(3), P(4-XC6H4)(3); X = H. OMe, F] modulate the intens ity and position of the correlations in the rhodium dimension; cross peaks are displaced from the true chemical shift, additional cross peaks are seen , and the intensity of the coherences varies as a function of the mixing ti me and coupling constant, going to zero at the conventional value of 1/(2J) .
