What could be the probable reason for splitting of the ESR peak (as attached)?

16 February 2023 1 9K Report

I have a solid state X-band ESR spectra of an organic compound, as attached here. Unlike normal spectra, the spectra of my compounds seems to be peculiar in nature. What could be the possible reasons for splitting of the peak on the left side of the spectra?

Anisotropic g tensor maybe? g(X) different g(y) different g(z), try orienting the crystal in different directions.
