PLUSH TACSY: Homonuclear planar TACSY with two-band selective shaped pulses applied to C-alpha,C' transfer and C-beta,C-aromatic correlations

Abstract

A new homonuclear Hartmann-Hahn-type mixing scheme is introduced that effects coherence transfer between resonances in two separated frequency bands. The mixing scheme relies on the irradiation of two-band selective shaped pulses that are expanded in an MLEV-16 supercycle. Similar to heteronuclear Hartmann-Hahn experiments, a planar effective coupling tenser is created. This novel mixing scheme is applied to C-alpha,C' transfer and to the transfer between C-beta and aromatic carbon spins.
