Multiple FID Acquisition of Complementary HMBC Data

One experiment, four NMR spectra : By combining the principles of time‐sharing evolution and multiple FID acquisition within the same scan, several fully complementary NMR spectra can be obtained in a single‐shot acquisition. Four different HMBC and HMBC‐relayed experiments (see spectra) can be carried out simultaneously for 13 C and 15 N at natural abundance, with a saving in measuring time of up to 75 %.
