Selective control of states of a three-level quadrupolar nucleususing non-selective radio-frequency pulses

摘要

The scheme for obtaining the composite operator of the selective rotation from nonselective RFpulses separated by intervals of free evolution has been proposed for quadrupole nuclei. On anexample of three levels, it has been shown that the rotation by this operator is performed withaccuracy comparable with the accuracy of a simple selective RF pulse, but in shorter time.
