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 = gμBB 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.
