This method is not designed to improve the sensitivity, but rather to reduce the experiment time, provided there is sufficient sensitivity. Therefore, it allows fast acquisition of such 2-D spectra in labeled molecules. The technique has been demonstrated using a U─13 C─15 N histidine hydrochloride monohydrate sample allowing each point of the build-up curves of the 13 C─13 C cross-peaks to be recorded within 4 min 35 s, which is very difficult with conventional methods. Using the U─13 C─15 N f-MLF sample, we have demonstrated that the method can be applied to molecules with 14 13 C resonances with a minimum frequency separation of 240 Hz.Show less >
