Magnitude-mode HMQC pulse sequence.

Syntax

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

Arguments

   parameters.sweep          [F1 F2] sweep widths in each
                             frequency direction, Hz

   parameters.npoints        [F1 F2] numbers of points in
                             each time direction

   parameters.spins          {F1 F2} nuclei, e.g. {'15N','1H'}

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

   parameters.decouple_f1    nuclei to decouple in F1, 
                             e.g. {'1H','13C'}

   parameters.J              primary 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 - free induction decay for magnitude mode processing

Examples

An HMQC spectrum of strychnine (examples/nmr_liquids/hmqc_strychnine.m) appears below.

Notes

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