Abstract:

Pulse sequences for heteronuclear single-quantum coherence (HSQC) and heteronuclear double-quantum coherence (HDQC) experiments for spin 1/2-spin 1 coupled spin systems were evaluated theoretically and experimentally. The results showed that zero-quantum transition occurs in the HDQC experiment. Therefore, this experiment in fact should be an HMQC experiment. The results also showed that HSQC experiment is more sensitive than HDQC experiment.

Key words: NMR, spin 1/2-spin 1 coupled system, HSQC, HDQC, deuterated benzene
