Magnitude-mode HMQC pulse sequence from https://doi.org/10.1016/0022-2364(83)90241-X.
Syntax
fid=hmqc(spin_system,parameters,H,R,K)
Parameters
parameters.sweep [F1 F2] sweep widths in each
frequency direction, Hz
parameters.npoints [F1 F2] numbers of points in
each time direction
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 that receive midpoint 180-degree
refocusing pulses in F1, e.g. {'1H'}
parameters.J primary 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 - free induction decay for magnitude mode processing
Examples
An HMQC spectrum of strychnine (examples/nmr_liquids/hmqc_strychnine.m) appears below.
Notes
Natural abundance experiments should make use of the isotope dilution functionality. See dilute.m function.
