Phase-sensitive COSY pulse sequence.

Syntax

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

Parameters

    parameters.sweep        sweep width in Hz

    parameters.npoints      number of points for both dimensions

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

    parameters.angle        second pulse angle in radians, usu-
                            ally pi/2, but also allows COSY45, 
                            COSY60, etc.

    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

Examples

A COSY90 spectrum of rotenone (examples/nmr_liquids/cosy90_rotenone.m) appears below.

Notes

If the second pulse angle differs from 90 degrees, magnitude mode plotting is advised.
