INADEQUATE pulse sequence. Selects double-quantum coherence from coupled carbon pairs, then converts it back into observable single-quantum magnetisation. At natural abundance 13C, this produces only 13C pair subspectra.
Syntax
fid=inadequate(spin_system,parameters,H,R,K)
Arguments
parameters.sweep sweep width in Hz
parameters.npoints number of points in the fid
parameters.spins active nuclei, e.g. {'13C'}
parameters.decouple nuclei to decouple, e.g. {'1H'}
parameters.J working J-coupling in 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
Examples
An INADEQUATE spectrum simulation for cyprinol (examples/nmr_liquids/inad_cyprinol.m) appears below.
Notes
Use dilute.m to generate carbon pair isotopomers.
