Abstract
A density matrix treatment is presented which describes the main features of INADEQUATE experiments for spin-1 AX spin systems. It is shown that apart from two-spin double quantum peaks, which carry correlation information, one-spin double quantum peaks are to be expected. In the latter, homoculear spin-spin coupling is amplified in the F1 domain where the signal splitting amounts to 4J. The theoretical predictions are verified for the 2H,2H AX system of 3,3'-[D2]norcamphor. In addition, experimental results for a 6Li,6Li A2X2 or AA'XX' spin system are presented and the influence of spin-lattice relaxation on the relative intensity of the one-spin double quantum peaks for 6Li,6Li experiments is demonstrated.
