Some common NMR experiments:
 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
 Connections through space（dipolar coupling）
1D、2D NOESY，ROESY, HOESY(HSQC-NOESY)
usage： connecting spin systems 、structure determination

COSY spectrum is used for determining the connectivities
between protons on the basis of geminal and vicinal couplings.
Disadvantage: bulky dispersive diagonal peaks.

mixing time
t1
Spin-lock

For small molecule NOE can be very small or zero，
ROESY can be used in place of NOESY experiment. ROE
intensity is also related to the H-H distances.
Structure Determination Procedures
1D 1H & 13C & DEPT (+MS、IR，basic chemical structure or
functional groups information）
Establish 13C-1H connections by thru bond JCH couplings
HMQC、HSQC、HSQC-TOCSY experiments
Establish 1H-1H connection (spin systems or partial pieces）
Decoupled 1H, 1D TOCSY, 2D 1H-1H COSY, TOCSY expts.
（usually starts with well-resolved 1H signals）
Long range connections（connecting spin systems & assigning
quaternary carbon）
1D NOESY & 2D HMBC, NOESY, ROESY experiments
3D structure or conformation determination
1D NOESY & 2D NOESY, ROESY, (HSQC)-NOESY expts.
