Magnitude mode PANSY-COSY pulse sequence from Figure 1a in the paper by Kupce, Freeman, and John: http://dx.doi.org/0.1021/ja0634876

Syntax

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

Arguments

   parameters.spins   - nuclei on which the sequence runs,
                        e.g. {'1H','13C'}

   parameters.sweep   - a vector with two sweep widths in Hz

   parameters.npoints - a vector of integers specifying 
                        point count in each dimension

   H - Hamiltonian matrix, received from context function

   R - relaxation superoperator, received from context function

   K - kinetics superoperator, received from context function

Outputs

   fid.aa - magnitude mode COSY FID on F1,F1 nuclei

   fid.ab - magnitude mode COSY FID on F1,F2 nuclei

Examples

An example of a PANSY-COSY simulation for camphor (examples/nmr_liquids/pansy_camphor.m) appears below.

Notes

Decoupling with respect to either of the working nuclei is impossible in this pulse sequence.
