class DEERSequence(*, tau1, tau2, tau3=None, tau4=None, dt, B, LO, reptime, averages, shots, ESEEM_avg=None, **kwargs)¶

Represents a DEER/PELDOR sequence.

Build a DEER sequence using rectangular pulses

Parameters:

tau1int or float: The first interpulse delay in us
tau2int or float: The second interpulse delay in us
dtint or float: The time step for DEER measurment in ns
Bint or float: The B0 field, in Guass
LOint or float: The LO frequency in GHz
reptime_type_: The shot repetition time in us
averagesint: The number of scans.
shotsint: The number of shots per point
tau3int or float, optional: The delay between the first static pump pulse in 5-pulse DEER and the 1st refocusing pulse in us, by default None. If the value is None then a 4-pulse sequence is created, otherwise a 5-pulse.
ESEEM_avg: str: Selecting the ESEEM averaging required. ESEEM averaging works by introducing small stepping in the first tau delay and averaging across them all. Options: * proton - 8 small steps of 8ns * deuteron - 8 small steps of 16ns * None - default

three_pulse(tp=16)¶

Build a four pulse DEER sequence.

Parameters:

four_pulse(tp=16, relaxation=False)¶

Build a four pulse DEER sequence.

Parameters:

five_pulse(tp=16, relaxation=False, re_step=50, re_dim=100)¶

Build a five pulse DEER sequence.

Parameters:

seven_pulse(tp=16, relaxation=False)¶

Build a seven pulse DEER sequence.

Parameters:

nDEER_CP(n, tp=16, relaxation=False, pcyc='Normal')¶

Generate an nDEER sequence.

The sum of tau1 and tau2 is used as total trace length.

Parameters:

nint: The number of refocusing pulses
tpint, optional: _description_, by default 16
relaxationbool, optional: _description_, by default False
pcyc: str, optional: Normal: Phases cycles pump and observer pulses, no DC cycle NormalDC: Phases cycles pump and observer pulses, DC cycle Obs: Phases cycles observer pulses, no DC cycle ObsDC: Phases cycles and observer pulses, DC cycle
