2-D Correlations http://www.univ-lille1.fr/lcom/RMN2D/resum2D_us/index1.htm#p07_us.htm
Description of some commonly used experiments useful for homonuclear (COSY, DQF-COSY, Relayed-COSY, TOCSY, ROESY)and heteronuclear correlation (XHCORR, COLOC, 2D-J resolved) with diagrammatic representation of pulse sequences. Some sample spectra are included.
Advanced NMR course http://web.chem.queensu.ca/FACILITIES/NMR/nmr/webcourse/index1.htm
Concise explanations of pulse sequences commonly used in studies of organic compounds (vector model graphics and some animations for clarifying the concepts). Covers basic concepts of pulsed NMR, including phase-cycling, building blocks, decoupling, 2D homonuclear and heteronuclear experiments, 3D NMR etc.
