Components of the Pulse FT-NMR Experiment

This section will cover the most important parameters which affect any spectrum you may collect using an FT-NMR spectrometer. The standard names of the parameters and the specific names (in bold) by which these parameters are referred to on the Unity+300 and VXR-S 400 NMR spectrometers are listed below.

Spectrometer Frequency sf

Pulse Width pw

Acquisition Time at

Number of Points np

Spectral width sw

Relaxation Delay d1

The generic 1PULSE FTNMR experiment is illustrated in Figure II-1. The experiment essentially

Consists of three components: relaxation delay, pulse width and acquisition time, and is named a 1PULSE experiment because one radiofrequency (rf) pulse is applied per cycle or transient.
