Magnitude-mode HETCOR pulse sequence.
Syntax
fid=hetcor(spin_system,parameters,H,R,K)
Arguments
parameters.sweep [F1 F2] sweep widths in the
two frequency directions, Hz
parameters.npoints [F1 F2] numbers of points in
the two time directions in fid
parameters.spins {F1 F2} nuclei (e.g. {'1H','13C'})
parameters.decouple list of nuclei that detection
time decoupling should be applied
to - cell array of strings, e.g.
{'1H','15N'})
parameters.J working scalar coupling, Hz
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 for magnitude-
mode processing
Examples
A HETCOR spectrum of strychnine (examples/nmr_liquids/hetcor_strychnine.m) appears below.
Notes
Natural abundance experiments should make use of the isotope dilution functionality. See dilute.m function.
