hyscore.m

HYSCORE experiment, implemented as described in Szosenfogel and Goldfarb (http://dx.doi.org/10.1080/00268979809483260).

Syntax

    fid=hyscore(spin_system,parameters,H,R,K)

Parameters

   parameters.nsteps          number of points to be computed 
                              in each dimension

   parameters.sweep           sweep width, Hz

   parameters.tau             tau delay, seconds

   parameters.rho0            initial state

   parameters.coil            detection state

   H  - Hamiltonian matrix, received from context function

   R  - relaxation superoperator, received from context function

   K  - kinetics superoperator, received from context function

Outputs

    fid  - two-dimensional free induction decay that Fourier
           transforms into a HYSCORE spectrum

Examples

A powder-averaged HYSCORE of a 14N nitroxide radical reproducing Figure 2a from http://dx.doi.org/10.1080/00268979809483260 is available in examples/esr_solids/hyscore_powder.m file. The output is reproduced below.

Notes

The sequence uses ideal pulses, replace with shaped_pulse_af.m to have soft pulses instead.
