Oneshot DOSY pulse sequence.
Syntax
fid=dosy_oneshot(spin_system,parameters,H,R,K,G,F)
Parameters
parameters.rho0 - initial state
parameters.coil - detection state
parameters.spins - nuclei on which the sequence runs
parameters.g_amp - gradient amplitude for diffusion encoding, T/m.
parameters.g_dur - pulse width of the gradient for diffusion encoding, s.
parameters.kappa - unbalancing factor to unbalance the bipolar gradients in the ratio (1+kappa):(1-kappa).
parameters.g_stab_del - gradient stabilisation delay, s
parameters.del - diffusion delay, s
parameters.dims - size of the sample, m
parameters.npts - number of discretization points in the grid
parameters.npoints - number of points in the acquired signal
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
Examples
An example is available in Spinach in: examples/nmr_spen/dosy_oneshot_1.m.
