Magnitude-mode HMBC pulse sequence from A. Bax and M.F. Summers, J. Am. Chem. Soc., 108, 2093 (1986).
Syntax
fid=hmbc(spin_system,parameters,H,R,K)
Arguments
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.J primary scalar coupling, Hz
parameters.delta_b delta_2 delay from the paper
cited above; the authors recom-
mend 60e-3 seconds
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
A simulated HMBC spectrum for camphor (examples/nmr_liquids/hmbc_camphor.m) appears below.
Notes
Natural abundance experiments should make use of the isotope dilution functionality. See dilute.m function.
