Phase-sensitive homonuclear NOESY pulse sequence.

Syntax

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

Arguments

   parameters.sweep     sweep widths, Hz

   parameters.npoints   number of points for both dimensions

   parameters.spins     nuclei on which the sequence runs,
                        specified as '1H', '13C', etc.

   parameters.tmix      mixing time, seconds

   parameters.rho0      initial state; skip this and specify
                        parameters.needs={'rho_eq'} to start
                        from exact thermal equilibrium

   H - Hamiltonian matrix, received from context function

   R - relaxation superoperator, received from context function

   K - kinetics superoperator, received from context function

Outputs

   fid.cos,fid.sin - two components of the FID for F1 hyper-
                     complex processing

Examples

A NOESY simulation for strychnine may be found in examples/nmr_liquids/noesy_strychnine.m file. The output is shown below.

Notes

This function is used for extreme simulations (proteins and nucleic acids) - its layout is optimised for minimum memory footprint rather than CPU time.

Chemical exchange is supported, just specify your kinetic processes as described in the kinetics chapter.
