Magnitude-mode HETCOR pulse sequence.

Syntax

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

Arguments

   parameters.sweep         [F1 F2] sweep widths in the 
                            two frequency directions, Hz

   parameters.npoints       [F1 F2] numbers of points in 
                            the two time directions in fid

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

   parameters.decouple      list of nuclei that detection 
                            time decoupling should be applied
                            to - cell array of strings, e.g.
                            {'1H','15N'})

   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 - two-dimensional free induction decay for magnitude-
          mode processing

Examples

A HETCOR spectrum of strychnine (examples/nmr_liquids/hetcor_strychnine.m) appears below.

Notes

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