✦ Synopsis

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 F, domain where the signal splitting amounts to 45. The theoretical predictions are verified for the 'H,'H AX system of 3,3'-[D,]norcamphor. In addition, experimental results for a 6Li,6Li A,X, or A A X X 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.
