【Abstract】 A pulse gradient field instrument for pulse gradient-enhanced high-resolution NMR was developed on Bruker MSL 300 spectrometer. The system was composed of a modified 1H liquid probe and a PC-controlled pulse gradient field generator whose waveform and amplitude can be arbitrarily set. The eddy-current effect caused by the gradient field was analyzed and a gradient-enhanced COSY experiment was also carried out to test this instrument.更多还原
