| Abstract: | Mossbauer spectra of Fe(pyridine)2Cl2 have been determined in large external magnetic fields at room temperature and 78 K. The principal component of the electric field gradient tensor is positive and consistent with an electron in the dxy orbital. The results indicate no change in orbital ground state for the low temperature phase transition of this material. |
