NMR SIMULATING PROGRAM USING PRODUCT OPERATORS
Simulation using product operators is crucial for understanding the workings of NMR experiments.
Manual application of this model can be very time-consuming with complex pulse sequences and is often characterized by input errors.
Therefore, a suitable program that can handle this is desirable.
SIM3, an older but quite powerful program, is now included in this tutorial:
NMR EXPERIMENTS --> MORE DETAILED INFORMATION ON THE PRODUCT OPERATOR FORMALISM
Its versatility stems from the fact that the results are available in both the Cartesian and spherical bases:
- Tracking of the evolution of a spin system in the course of a pulse sequence in the form of Cartesian operators allows the evolution of a spin system to be followed (and understood) more easily via the directly related and visualized macroscopic magnetizations.
- The spherical basis, on the other hand, also enables the understanding and efficient modeling of the coherence transfer pathways traversed during a pulse sequence.
This is essential for incorporating magnetic field gradients and understanding their influence on a spin system.
As will be shown in the following chapters, magnetic field gradients are now an indispensable tool in the development of high-performance pulse sequences.
