DEPTQ pulse sequence from Figure 1 of the paper by Burger and Bigler (https://doi.org/10.1006/jmre.1998.1595).

Syntax

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

Arguments

   parameters.sweep              [F1] Sweep width in Hz

   parameters.npoints            [F1] number of points

   parameters.spins              {F1,F2} nuclei, e.g. {'13C','1H'}

   parameters.J                  working J-coupling in Hz
 
   parameters.beta               the angle used in the selection
                                 pulse, radians

   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

Examples

The simulation of a DEPTQ135 spectrum of strychnine (examples/nmr_liquids/deptq_strychnine.m) appears below.

Notes

  1. Use dilute.m to generate carbon isotopomers.
  2. The sequence differs from dept.m in that quaternary carbons do appear.
