Phase-sensitive HSQC pulse sequence. Syntax:

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

where H is the hamiltonian commutation superoperator, R is the relaxation superoperator and K is the chemical kinetics superoperator. The following parameters are required:

parameters.sweep              [F1 F2] sweep widths, Hz
parameters.npoints            [F1 F2] numbers of points
parameters.spins              {F1 F2} nuclei (e.g. '13C','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                  scalar coupling, Hz

Note: States quadrature detection is used; the two components of the States signal are returned in fid.pos and fid.neg structure fields.

Note: natural abundance experiments should make use of the iso- tope dilution functionality. See dilute.m in the kernel.
