Deer 3p hard echo.m
Samples the spin echo in the three-pulse DEER experiment for the purposes of determining its precise location. This is necessary in high-spin elec- tron systems for which the echo might not be in the expected place.
parameters.ex_prob - probe pulse operator
parameters.ex_pump - pump pulse operator
parameters.ta - time between first and third pulse
parameters.tb - time between first and second pulse
parameters.tc - time interval to sample around the echo
parameters.rho0 - initial condition
parameters.nsteps - number of sampling steps in tc interval
parameters.coil - detection state
Note: always run this experiment before simulating DEER traces. DEER spin echo can be very narrow and easy to miss.
