WebThe temperature of a sample in the probe of an NMR spectrometer can be determined from the separation between two peaks in a 1H NMR spectrum of a standard 'NMR thermometer' sample. Measure the 1H-NMR spectrum of the NMR thermometer Deuterated samples should be locked and acquired as normal. WebLook for a broad peak anywhere from 1-6 ppm. Most often though it will be in the 4-6 range. Remember also that the OH signal is not split by adjacent protons unless the sample is very dry. Other groups that give broad, and sometimes, deuterium-exchangeable signals are the amines, amides, and thiols. Carboxylic acids
