I've doped a nanomaterial with an electron donor, the X-band ESR spectra does indicate that there is a change in the line widths of both the spectra along with a slight change in the g-factor values. Does this indicate a change in the electronic environment of the nanomaterial? For example can it be conclude that a charge transfer is taking place? The spectra is attached. The dark yellow spectra is only of the nanomaterial. The orange spectra is after the addition of the electron donor
