How NMR Spectrometers Record Signals

Description

NMR spectrometers record signals from samples that contain NMR-active nuclei. The system uses a strong magnet, a radiofrequency transmitter, and a detector connected to a computer console. These parts work together to measure and display the spectrum of the sample.

Early NMR instruments were cont...

Transcript

NMR spectrometers consist of a strong magnet, a radiofrequency or rf transmitter, and a detector attached to a computer console.

First-generation NMR instruments called continuous-wave spectrometers record spectra using the frequency-sweep or the field-sweep methods.

While resonance frequencies are determined by fixing the magnetic...
