✦ Synopsis


The quadrupolar and dipolar interactions of spins during the radio frequency (RF) pulses are considered. It is shown that due to these interactions the two-pulse echo signal is observed at the shifted time t, = T + t,/2 (t, = width of the first RF pulse, 7 = time interval between the pulses).

The effects of nonzero radio-frequency pulse widths on the echo signals in solids with molecular motions have been investigated. It has been shown that in the slow-motion region a time position and an amplitude of the echo signal depend not only on the width of the pulse, but also on the shape of po

The shape of the free induction decay for the case in which the amplitude B, (B, = 0,/y) of the RF pulse is comparable with local magnetic fields at sites of the nuclei is considered. It is shown that the shape of the FID G(r + T) (where T is the width of a RF pulse, t is the time after a RF pulse)

There have been theoretical studies presented that postulate a change in the stimulus current amplitude required to recruit nerve fibers with different stimulus current pulse widths. Based on these theoretical predictions, it has been suggested that the stimulus pulse width parameter may be used to
