COLOC NMR pulse sequence from https://doi.org/10.1016/0022-2364(84)90136-7, implemented as shown in Figure 1b, without the dashed pulses during the delta(2) period. Delta(1) defaults to half of the maximum F1 evolution time implied by the sweep width, delta(2) must be specified.
Syntax
fid=coloc(spin_system,parameters,H,R,K)
Parameters
parameters.sweep [F1 F2] sweep widths, Hz
parameters.npoints [F1 F2] numbers of points
parameters.spins {F1 F2} nuclei (e.g. '13C','1H')
parameters.delta2 COLOC delta2 (see the paper),
typically 40e-3 seconds
parameters.delta1 optional COLOC delta1 delay, seconds;
must be at least half of maximum t1
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
An example may be found in examles/nmr_liquids/coloc_test.m file, its output appears below.
Notes
Natural abundance simulations should make use of the isotope dilution functionality. See dilute.m function.
