摘要: Several cooperative vibronic bands have been observed in the excitation and emission spectra of polycrystalline hydrates dilute aqueous solutions TbCl3. A radiative transition involving simultaneous electronic a Tb3+ ion vibrational nearby water molecule gives rise to these bands. Theoretical calculations, based on an electrostatic coupling model, explain intensities transitions. Selection rules are derived quantitative estimates made.
