PG - 331-4 LID - 10.1023/A:1008360013567 [doi] AB - We show that adiabatic fast passage (AFP) pulses are robust refocusing elements of transverse (13)C magnetization in multidimensional NMR experiments. A pair of identical AFP pulses can refocus selected parts or a complete (13) C chemical shift range in (13)C spectra. In the constant time (13)C-(1)H HSQC, replacement of attenuated rectangular pulses by selective AFP pulses results in a sensitivity enhancement of up to a factor of 1.8. In the 3D CBCA(CO)NH the signal-to-noise ratio is increased by a factor of up to 1.6.
