NMR Pulse Angles and Signal Collection

NMR pulse angles and signal collection explain how radiofrequency energy starts a measurement. A pulse is a short burst of radio waves spread across a range of frequencies. It excites the nuclei in the sample at the same time.

When a radiofrequency pulse is applied along the x-axis, nuclei absorb...

A pulse is a short burst of high-power rf radiation that includes the Larmor frequencies of the observed nuclei in a sample.

As the nuclei absorb energy, the net magnetization vector shifts toward the transverse plane.

This angle of rotation, or the flip angle, of the magnetization vector, is proportional to the pulse duration and ...
