Cross-Polarization (CP) and Magic-Angle spinning (MAS). The CP experiment (CP-MAS) Variable-amplitude Cross-polarization (VACP) Sideband suppression: TOSS (Total suppression of spinning sidebands) 2D separation of spinning sidebands patterns: PASS (Phase Adjusted Spinning Sidebands) ( 95JMRA7-115 and 97JACS3807 ) SELTICS (Sideband Elimination by Temporary Interruption of the Chemical Shift) IRS (Isotropic Rotation Sequence) Heteronuclear Decoupling: ( 05PROG197 ) High power CW decoupling TPPM; Two pulse phase modulation XiX Other: FMPM, SPARC, C12, SPINAL and amplitude modulated TPPM Adiabatic Decoupling ( 04JB319-29 ) Homonuclear Decoupling WAHUHA MREV-8 CRAMPS: Combined Rotation And Multiple Pulse Sequence. TO synchronize the sample spinning and the decoupling sequence accurately. Constant-time-CRAMPS (CT-CRAMPS). Frequency-switched Lee-Goldburg (FSLG) scheme: when homonuclear decoupling is required only inthe indirectly-detected dimension. Phase-Modulated Lee-Goldburg (PMLG) experiment.
