Rotor-synchronous MQMAS pulse sequence.

Syntax

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

Arguments

    parameters.pulse_dur - duration of each pulse, a two-
                           element vector, seconds

    parameters.pulse_amp - amplitude of each pulse, a two-
                           element vector, rad/s
 
    parameters.mq_order  - MQMAS coherence order
 
    parameters.rho0      - initial condition, usually Lz

    parameters.coil      - detection state, usually L+

    + the parameters required by the singlerot.m
      context function that will provide H, R, and K

Outputs

    fid - 2D amplitude mode free induction decay

Examples

An example of this sequence being run on a quadrupolar system is given in examples/nmr_solids/mqmas_nqi.m file.

Notes

The sequence is rotor-synchronous - parameters.sweep should be set equal to parameters.rate
