inv_rec.m

Inversion-recovery pulse sequence.

Syntax

fids=inv_rec(spin_system,parameters,H,R,K)

Arguments

parameters.sweep spectrum sweep width, Hz

   parameters.npoints            number of points in the FID

   parameters.spins              nuclei on which the sequence runs,
                                 specified as {'1H'}, {'13C'}, etc.

   parameters.max_delay          longest relaxation delay

   parameters.n_delays           number of relaxation delays to run

   H     - Hamiltonian matrix, received from context function

   R     - relaxation superoperator, received from context function

   K     - kinetics superoperator, received from context function

Outputs

fids - free induction decays for each delay starting from zero,

           a matrix with individual FIDs in columns

Note: the relaxation superoperator must be thermalised.

Examples

A simulation of a inversion-recovery experiment on strychnine (examples/nmr_liquids/sat_rec_strychnine.m) appears below - it is a stack of spectra obtained after different relaxation delays.

Notes

The relaxation superoperator must be thermalised.
