hmbc.m

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.
