Deer 3p hard deer.m
Three-pulse DEER pulse sequence. Idealized hard pulses are used, each pulse only affects its specific electron. Syntax:
where H is the Hamiltonian commutation superoperator, R is the relaxation superoperator and K is the chemical kinetics super- operator. The following parameters are required:
parameters.rho0 initial state
parameters.coil_prob detection state on probe spin
parameters.stepsize increment time for the pump pulse sandwich
parameters.nsteps number of steps for the pump pulse sandwich
parameters.ex_prob excitation operators to be used for parameters.ex_pump the probe and pump electron respec- tively -- hard pulses are only app- ropriate for spin-1/2 systems, for higher spin systems transition se- lective operators must be supplied.
parameters.output 'brief' returns just the DEER trace, 'detailed' also returns excitation profiles and the EPR spectrum.
If 'detailed' is selected as the output option, the following para- meters are also required:
parameters.ex_hard hard pulse excitation operator
parameters.spectrum_sweep sweep width of the EPR spectrum, Hz
parameters.spectrum_nsteps number of time steps in the FID
parameters.coil_pump detection state on pump spin
