"Kin " HEHAHA Sequences, Heteronuclear Hartmann-Hahn Transfer with Different Bandwidths for Spins I and S

.   

Abstract

A new class of heteronuclear Hartmann-Hahn experiments that is based on the simultaneous irradiation of two different multiple-pulse sequences is introduced. For these "kin " HEHAHA sequences, the scaling properties of the effective heteronuclear coupling constants are analyzed. Four kin sequences are presented with a ratio of the active bandwidths DeltanuI /DeltanuS ranging between 1/2 and 1/10. The offset dependence of the polarization-transfer efficiency is examined experimentally and with the help of numerical simulations.
