Syntax

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

Parameters

    parameters.sweep              [F1 F2] sweep widths, Hz

    parameters.npoints            [F1 F2] numbers of points

    parameters.spins              {F1 F2} nuclei (e.g. '13C','1H')

    parameters.decouple_f2        nuclei to decouple in F2, e.g. 
                                  {'15N','13C'}

    parameters.decouple_f1        nuclei that receive midpoint
                                  180-degree refocusing pulses in
                                  F1, e.g. {'1H','13C'}

    parameters.J                  working scalar coupling, Hz

    H  - Hamiltonian matrix, received from context function

    R  - relaxation superoperator, received from context function

    K  - kinetics superoperator, received from context function

Outputs

    fid.pos,fid.neg -  two components of the States quadrature 
                       signal.

Examples

An HSQC spectrum of strychnine with natural abundance of 13C (examples/nmr_liquids/hsqc_strychnine.m) appears below.

Notes

Natural abundance simulations should make use of the isotope dilution functionality. See dilute.m function.
