A new hardware-based approach is presented to reduce data acquisition times in multi-dimensional NMR spectroscopy using a
multiple-coil probe. Using a four-coil setup, two-dimensional COSY and TOCSY spectra were acquired in one-quarter the time of
conventional spectra by simultaneous acquisition of different effective t1 evolution times for each coil. Data processing consists of
simple phase-shifting and intensity normalization of the individual data sets, and results in spectra almost identical to those acquired
in a conventional manner. This method can potentially be integrated with other new data acquisition and processing schemes for
further increases in data acquisition speed.
