Abstract
The temperature of an NMR sample can be indirectly determined by using a suitable deuteriated reference compound and the lock channel for observing the deuterium rapid‐passage NMR spectrum. By calculating the autocorrelation spectrum by two forward Fourier transformations, the relative chemical shift differences can easily be determined. The procedure can be performed on most commercial spectrometers and is completely independent of the frequency of the observed nucleus and/or any high‐power proton decoupling of the sample.Keywords
