Heteronuclear Multiple Quantum Coherence (HMQC) and Heteronuclear Multiple Bond Coherence (HMBC) are 2-dimensional inverse H,C correlation techniques that allow for the determination of carbon (or other heteroatom) to hydrogen connectivity. HMQC is selective for direct C-H coupling and HMBC will give longer range couplings (2-4 bond coupling). Our facility implements gradient-selected versions of both HMQC (gHMQC) and HMBC (gHMBC), which improves the acquired spectra by significantly reducing unwanted signal artifacts.
