class Eco(Freq=9.433, Points=4096, Temperature=295.15, Fdirection=<factory>, Mwdirection=<factory>, Frange=<factory>, Sampleframe=<factory>, Molframe=<factory>, gframe=<factory>, Aframe=<factory>, Dframe=<factory>, Qframe=<factory>)#

Bases: object

Container class for the experimental parameters. Must be initialized with a variable like Exp. To change one parameter use the sintaxis Exp.Freq=9.40.

Parameters:

  • Freq (float) – Frequency of the microwave in the EPR spectrometer in GHz.

  • Points (int) – Number of points used to take the EPR spectrum.

  • Temperature (float) – Temperature of the sample during the measurement in Kelvin.

  • Fdirection (list=[0,0,1]) – Direction of incidence of the magnetic field in relation with the lab frame. By deafult it’s [0,0,1], the Z direction.

  • Mwdirection (list=[1,0,0]) – Direction of incidence of the microwave radiation in relation with the lab frame. By deafult it’s [1,0,0], the X direction.

  • Frange (list=[0,1]) – Field range used in the EPR spectrum in mT.

  • Sampleframe (list==[0,0,0]) – Three Euler angles of the orientation of the sample in relation to the lab frame.

  • Molframe (list=[0,0,0]) – Three Euler angles of the orientation of the paramagnetic molecule in relation to the sample frame.

  • gframe (list=[0,0,0]) – Three Euler angles of the orientation of the tensor g in the molecular frame.

  • Aframe (list=[0,0,0]) – Three Euler angles of the orientation of the tensor A in the molecular frame.

  • Dframe (list=[0,0,0]) – Three Euler angles of the orientation of the tensor Q in the molecular frame.

  • Qframe (list=[0,0,0]) – Three Euler angles of the orientation of the tensor D in the molecular frame.
