Abstract: An auxiliary programmable controller for multiple pulse sequences (PCMP) based on a microprocessor is described in the paper. Attached the PCMP to a routine NMR spectrmeter for liquids, many MP experiments can be accomplished, namely, CRAMPS for isotropically chemical shift with J-coupling in organic solids, chemical shift scaling, time-averaged procession frequency cross-polarization, and broad-band decouplig with composite pulses as well, which improve the cababilities of a routine NMR spectrometer greatly.
