One-pulse sequence with pulse length p1 for nutation NMR

The one-pulse sequence is the simplest NMR experiment. The corresponding one-dimensional nutation method allows us to determine the quadrupole coupling in a single crystal. Furthermore, for short pulse length p1, the central-line intensity is independent of the quadrupole coupling and proportional to p1. This excitation condition of quadrupole spins in a single crystal allows us to quantify the number of spins in the crystal. However the acquisition delay or the "dead time" of the NMR probe head modifies the line intensity.

IMAGE: Parameters for the simulation of one-pulse nutation NMR line intensity

The left part of the simulation panel indicates the physical parameters. It is preset for a typical experiment on a spin I = 3/2. You can introduce your own values.

MinLength: the first value of p1 in µs

MaxLength: the last value of p1 in µs

Step: the increment of p1 in µs

The following applet is initialized for the central-line intensity of a spin I = 3/2 in a single crystal excited by the one-pulse sequence. The experimental line intensities are identical to the simulated ones.
