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.
