Sentence examples for nmr spectrometers from inspiring English sources
Here, we describe the design and performance of a quasi-optical system enabling the use of a single 395 GHz gyrotron microwave source to simultaneously perform DNP experiments on two different 14.1 T (1H 600 MHz) NMR spectrometers: one configured for magic angle spinning (MAS) solid state NMR; the other configured for solution state NMR experiments.

The design and application of a versatile and inexpensive experimental extension to NMR spectrometers is described that allows to carry out highly reproducible PHIP experiments directly in the NMR sample tube, i.e. under PASADENA condition, followed by the detection of the NMR spectra of hyperpolarized products with high spectral resolution.
In modern NMR spectrometers, organic compounds are placed in magnetic fields ranging from about 1.4 to 18.0 teslas (T) and are irradiated with radio-frequency waves.
NMR spectrometers have a feature, called integration, which, when selected by the user, calculates the area under each peak and plots the result as a line that is displaced vertically at a peak by an amount proportional to the area under the peak.
These magnets can potentially be used in medium-resolution NMR spectrometers and high-field NMR spectrometers.
