HOMONUCLEAR CORRELATION EXPERIMENTS WITH QUADRUPOLAR NUCLEI

The fine-structure of COSY signals from spin-1 AX systems has been cal culated within the framework of the product operator formalism and sim ulated numerical density matrix calculations with the program SMART. T he theoretical predictions have been verified experimentally for the d euteron AX system of 3,3'-norcamphor, where the homonuclear H-2, H-2 c oupling is 0.35 Hz. By comparing the H-2, H-2 COSY experiment with the 2D-H-2, H-2 TOCSY experiment for azulene-d(g), it was shown that magn etisation transfer is more efficiently detected by the TOCSY sequence. Finally, several Li-7, Li-7 COSY experiments for an organolithium com pound are reported for the first time.
