Apr 16, 2022 · A pulse sequence is a succinct visual representation of the pulses and delays used in a certain NMR experiment. Depending on the experiment there may be hundreds of pulses! …
Pulse sequence - Wikipedia
In Fourier transform NMR spectroscopy and imaging, a pulse sequence describes a series of radio frequency pulses applied to the sample, such that the free induction decay is related to …
Pulse phases are relative phases with respect to the reference phase for signal detection. The phase programs are specified behind the pulse statements, and defined at the end of the …
experimental technique, called \pulsed NMR" (PNMR), was introduced in 1950 by Erwin Hahn. Pulsed NMR is used in magnetic resonance imaging (MRI). Purcell and Bloch won the Nobel …
The most basic and common pulse sequence you will encounter is the ‘1-PULSE’ FT-NMR experiment (e.g. seqfil = ‘s2pul’ in VNMR), which is the sequence used for routine 1 H and 13 …
NMR Pulse - an overview | ScienceDirect Topics
NMR experiments are classified in terms of NMR pulse scheme and cross-peak nature. A discussion about simplicity, general applicability and accuracy for each particular NMR …
The Basics of NMR
A pulse sequence is a set of RF pulses applied to a sample to produce a specific form of NMR signal. The 90-FID Sequence In the 90-FID pulse sequence, net magnetization is rotated …

The QCPMG pulse sequence is utilized to enhance signal to noise for nuclei possessing broad NMR patterns and suitably long transverse relaxation time constants (T2). The sequence …
Determining 90° and 180° Soft Pulses - Blogger
Feb 24, 2014 · The 90° pulse is at the first maximum and the 180° pulse is at the first null. Since the duration of a the selective pulse is fixed by the desired selectivity, the 90° and 180° pulses …
Pulse sequences and the vector model
Pulse sequences are used to excite signals that are observed in an NMR spectrometer. They range from general purpose single-pulse experiments to complex highly sophisticated …
