1D pulse-acquire NMR sequence with DPFGSE signal suppression, based on Equation 3 from Stott et al. (https://doi.org/10.1006/jmre.1997.1110); the spatial coordinate is modelled explicitly, and the function should be called through the imaging.m wrapper.
Syntax
fid=dpfgse_suppress(spin_system,parameters,H,R,K,G,F)
Parameters
parameters.rho0 - initial condition parameters.coil - detection state parameters.g_amp - amplitudes of the two gradients, T/m parameters.g_dur - gradient duration, seconds parameters.rf_frq_list - soft pulse parameters that will parameters.rf_amp_list be passed to shaped_pulse_af.m parameters.rf_dur_list function parameters.rf_phi parameters.max_rank parameters.sweep - detection sweep width, Hz parameters.npoints - number of points in the fid parameters.offset - transmitter and receiver offset, Hz
Outputs
fid - free induction decay of what is effectively a
1D pulse-acquire NMR experiment
Notes
At least a hundred points are required in the spatial dimension; increase until the answer stops changing.
