NORD: NO Relaxation Delay NMR Spectroscopy

The novel concept of NORD (NO relaxation delay) NMR spectroscopy is introduced. The idea is to design concatenated experiments in a way that the magnetization used in the first relaxes toward equilibrium during the second and vice versa, thus saving instrument time. Applications include complete wel...

Summary:The novel concept of NORD (NO relaxation delay) NMR spectroscopy is introduced. The idea is to design concatenated experiments in a way that the magnetization used in the first relaxes toward equilibrium during the second and vice versa, thus saving instrument time. Applications include complete well‐resolved 1H‐1H and 1H‐13C one‐bond and long‐range correlation maps of an 80 mM solution of a trisaccharide recorded in less than two minutes and hydrocortisone with extensive spectral overlap. NORD (NO relaxation delay) NMR spectroscopy is introduced and combined with concatenation of experiments in a way making relaxation delays unnecessary and thus enhancing overall sensitivity.
