ABSTRACT:
A method of nuclear magnetic resonance investigation of a repeated electromagnetic event in a sample comprises modulation of the nuclear spin polarization achieved during the recovery period between the final magnetic resonance signal detection period of one cycle and the initial signal generation RF pulse of the next cycle. This modulation is performed by giving the sample a different exposure to RF radiation in the different periods, for example by exposure to a different number of 180.degree. pulses in each period or by exposure to a frequency modulated continuous wave RF signal.
