NMR Applications in Chemistry
Some common NMR experiments:
2D COSY — Homonuclear Shift COrrelation SpectroscopY
2D Gradient COSY-45
2D DQF－COSY(Double-Quantum Filtered COSY)
2D Gradient DQF-COSY
TOCSY (TOtal Correlation SpectroscopY) or
HOHAHA(Homonuclear Hartman-Hahn Spectroscopy)
2D Gradient TOCSY, mixing time=20ms
2D Gradient TOCSY, mixing time=50ms
DEPT: Distortionless Enhancement by Polarization Transfer
HETCOR (Heteronuclear chemical shift correlation, 1H - 13C COSY)
HMQC (Heteronuclear Multiple Quantum Coherence)
HSQC (Heteronuclear Single Quantum Coherence)
HSQC spectrum: H-C correlated
HSQC-TOCSY
Gradient HSQC-TOCSY(mixing time=80ms)
HMBC (Heteronuclear Multiple-Bond Correlation Spectroscopy)
Gradient HMBC
2D NOESY (Nuclear Overhauser Enhancements SpectroscopY)
Gradient NOESY
2D ROESY pulse program
Structure Determination Procedures
=========
q Connections through bonds（spin-spin coupling）
Homonuclear： 1D、2D 1H-1H COSY, DQF-COSY, TOCSY
usage：spin system assignment
Heteronuclear：
Direct (detect 13C): APT, DEPT, HETCOR
Inverse (detect1H): HMQC, HSQC, HMBC, HSQC-COSY,
HSQC-TOCSY, HMQC-TOCSY
usage：assigning heteronuclei、connecting spin systems
q Connections through space（dipolar coupling）
1D、2D NOESY，ROESY, HOESY(HSQC-NOESY)
usage： connecting spin systems 、structure determination
