Kanzig, J. Phys. Chem. Solids 23, 479 (1962)."" en_US dc.description Author Institution: Laboratoire d'Optique Physique EPCI; Department of Chemistry, University of Southern California en_US dc.description.abstract Molecular ions such as $S_{2}^{-}$, $S_{3}^{-}$ or $Se_{2}^{-}$ may be introduced in alkali halides by heating the crystals close to their melting point in S or Se vapor. These ions ar usually $paraelastic^{1}$ above a characteristic temperature. We have measured their stress-induced linear dichroism and obtained detailed information regarding the identification of the ions, the assignment of their excited states and the ground state paraelastic relaxation. Measurements have been performed with a very sensitive apparatus and cover a wide range of temperatures $(300^{\circ}$ $K - 4^{\circ} K$ ). The possibility of studying the relaxation of the excited state will be discussed. en_US dc.format.extent 107704 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title PIEZOSPECTROSCOPIC STUDIES ON MOLECULAR IONS IN ALKALI HALIDES en_US dc.type article en_US
