Created page with "Magnitude-mode HMQC pulse sequence. Syntax: fid=hmqc(spin_system,parameters,H,R,K) where H is the hamiltonian commutation superoperator, R is the relaxation ..."

New page

Magnitude-mode HMQC pulse sequence. Syntax:

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

where H is the hamiltonian commutation superoperator, R is the
relaxation superoperator and K is the chemical kinetics super-
operator. 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. {'15N','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 primary scalar coupling, Hz

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