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)
Parameters
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
- This implementation is the DEPTQ135-style fixed first proton pulse variant. The beta parameter controls the last proton editing pulse.
- Use dilute.m to generate carbon isotopomers.
- The sequence differs from dept.m in that quaternary carbons do appear.
