Adiabatic TOCSY for C,C and H,H J-transfer

Adiabatic pulses have been widely used for broadband decoupling and spin in version at high magnetic fields. In this paper we propose adiabatic pulses and supercycles that can be used at high magnetic fields like 800 or 900 MH z to obtain broadband TOCSY sequences with C,C or H,H J-transfer. The new m ixing sequences are equal or even superior to the well known DIPSI-2,3 expe riments with respect to bandwidth. They prove robust against pulse miscalib ration and B-1 inhomogeneity and are therefore attractive for fully automat ed spectrometer environments. These adiabatic mixing sequences have been in corporated in a novel z-filter HCCH-TOCSY experiment.
