Field Sweeping Experiments

[adamnmr]

Are there any examples or experiments that feature propagation with a varying B0 field (i.e., where sys.magnet is dynamic or shaped)? A rough example might follow this sort of sequence:

initial field -> sweep to intermediate field -> RF pulse at freq0 -> sweep back to initial field -> RF pulse at freq1 -> detect observable

Just looking for the necessary syntax to do dynamic field sweeps and evolution.

Thank you.

Yep, Lines 71-74 in examples/parahydrogen/sabre_pyridine.m - you can request the Zeeman part and the coupling part of the Hamiltonian separately and then mix them manually as you wish. Careful with rotating frames though.
