EPR spectra of copper complexes with axial symmetry

EPR spectra of copper complexes with axial symmetry (X-band, 9.5 GHz) ?

g_⊥:

g_‖:

A_⊥ (MHz):

A_‖ (MHz):

Linewidth (G):

The orange line is an EPR spectrum of an unknown Cu complex.

Read the values of g_‖ and g_⊥ off the spectrum (the g factor is displayed in the top left corner of the spectrum).
Measure approximate values of A_‖ and A_⊥ off the spectrum (you can click on one peak and move the mouse, the distance is displayed on the blue background in the top left corner of the spectrum).
Convert the hyperfine values into MHz units using hν = gμ_BB equation.
Now let's simulate this spectrum! Drag the sliders to the values you determined. The red (simulated) spectrum should match the orange (experimental) one. You may have to adjust the line width to get a good match.
