2D multiple-quantum NMR pulse sequence from:

    https://doi.org/10.1002/cphc.201800667

    https://doi.org/10.1039/d1cc03079e

Syntax

    fid=mqs(spin_system,parameters,H,R,K)

Parameters

  parameters.sweep       [F1 F2] sweep widths (Hz)

  parameters.npoints     [F1 F2] numbers of points

  parameters.spins       working spins, e.g. {'1H','1H'}

  parameters.angle       flip angle, radians

  parameters.delay       J-coupling evolution delay, seconds

  parameters.mqorder     coherence order to select

  parameters.rho0        initial state

  parameters.coil        detection state

Outputs

    fid - 2D magnitude-mode free induction decay

Examples

See mqs_propanol.m file in examples/nmr_liquids directory.

Notes

This function should be invoked through liquid.m context, which would provide H, R, and K.

This is the non-refocused multiple-quantum/MaxQ variant. Use mqs_refocus.m when post-mixing refocusing is required.
