Ultrafast multiple-quantum NMR, a literal implementation of Figure 1A from (http://dx.doi.org/10.1002/cphc.201800667).
Syntax
fid=ufmq_nmr(spin_system,parameters,H,R,K,G,F)
Parameters
parameters.dims - size of the sample, m
parameters.npts - number of grid points in the sample
parameters.npoints - number of acquired points for each gradient readout
parameters.nloops - number of loop, where each loop consists of a positive
and a negative readout
parameters.offset - offset, Hz
parameters.Ga - acquisition gradient, T/m
parameters.deltat - timestep for acquisition, s
parameters.pulsenpoints - number of points in the pulse shape
parameters.BW - bandwidth of the pulse, Hz
parameters.Ge - encoding gradient, T/m
parameters.Te - duration of the pulse, s
parameters.chirptype - can be 'wurst' or 'smoothed'
parameters.smfactor - smoothing factor for the pulse
The last five parameters (H,R,K,G,F) are built automatically by imaging.m context function
when this sequence is called from that context.
Outputs
fid - free induction decay of the ultrafast NMR spectrum
