Because of this, 1H NMR without deuterium lock only works well on two NMR instruments: the 400SL and the 500 Ascend. 1. The lock and sweep must be off.
Shimming on non-deuterated solvents (“no-D”) Automatic Shimming + First run a one scan 1D proton spectrum without locking, so that you know where the solvent peak occurs. Use ns of 1 and ds of 0. Do [tune], [prosol], [gain], [go]. The following procedure will tell the instrument to not lock on deuterium, but use the proton signal
No deuterium (no-D) NMR is a technique that can be a useful alternative to using expensive deuterated solvents, if you are working with a neat sample, or want to directly monitor a reaction mixture. It is also useful for molecules of biomedical interest such as proteins, which must be studied in water (or 90% H 2O/10% D 2O).
No-Deuterium NMR | Nuclear Magnetic Resonance Facility
The No-D experiment skips the autolock step and shims on H instead of D. The No-D experiment also provides a "solvent suppression" method to partially remove the proton solvent resonance from the spectrum. Ideally a solvent for No-D NMR should have a …

2023年7月31日 · No-D NMR (5,6) is a technique for running NMR spectra without using deuterated solvents. The major problem to be overcome with this technique is shimming the sample since there is no deuterium signal to lock on. Using a capillary tube containing a deuterated sample placed inside the undeuterated sample is one solution to the problem.

The No-D NMR (No-Deuterium Proton NMR) technique is a measurement of high resolution 1H NMR spectra without using a deuterium solvent. With this technique many reaction mixtures or reagent solutions are directly available using protonated solvents.
Utilities of No-D NMR (No-Deuterium Proton NMR) - JEOL
No-D NMR (No-Deuterium Proton NMR) technique is a measurement of high resolution 1 H NMR spectra without deuterium solvent. It suggests that any reaction mixture or reagent solution are directly available for No-D NMR measurement.
