Obtaining EPR Spectrum

[Michelle Rodrigues]

conduct EPR spectroscopy and generate the EPR spectra for the sample at specific orientations of the applied field. From the absorption peaks in the spectrum, determine the local g-factor corresponding to the orientation of the applied field for that spectrum. Change the orientation of the applied field and measure the spectra again. Deduce the local g-factor values for the different spectra wrt the different applied fields. Since this is not the case of a free atom anymore, the g-factor is now a tensor quantity so the principle components of the g-factor tensor need to be derived. Finally, plot these values for the g-factor obtained against the orientation (angle in degrees) of the applied field.
