| Popis: | The flexibility in replacing the organic part of the organic-inorganic hybrid material has become an interesting material parameter to tune the functionality of their inorganic part. Based on the optical absorption in the UV-VIS region, we are able to observe the d-d transition of the Mn2+ in (C6H5CH2CH2NH3)2-MnCl4, and (NH2CH2CH2NH2)2-MnCl4 hybrid compounds. The results of this the experiment clearly indicate that there are six transitions related to the d-d transition of the Mn2+ from the high spin state, 6S, to the excited states of 4G, 4D and 4P. The transition energies are fitted to the Tanabe-Sugano diagram. The different in organic part change its Racah parameters and crystal field energy. This shows that the organic part could modify the bond strength between the Mn and the Cl as well as the electronic interaction. |
