One-shot 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

    parameters.sweep         - acquisition sweep width, Hz

    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.
