INFRARED SPECTRA OF MAGNESIUM HALIDES IN SOLID ARGON AND KRYPTON MATRICES

Author Institution: Space Science Laboratory, General Electric Company; Cryogenic Laboratory, The Ohio State UniversityThe infrared absorption spectra of magnesium fluoride and magnesium chloride isolated in solid krypton and argon matrices have been investigated from $240-4000 cm^{-1}$. The molecules were generated in a high temperature cell and trapped at liquid $H_{2}$ and He temperatures. The spectrum of $MgF_{2}$ indicates that the apex angle F---Mg---F is $160^{\circ} \pm 20^{\circ}$. Complete assignment and other details will be discussed

INFRARED ABSORPTION SPECTRA OF LiO, Li2OLi_{2} O AND Li2O2Li_{2}O_{2} IN SOLID KRYPTON MATRICES

Author Institution: Cryogenic Laboratory, The Ohio State University; Space Science Laboratory, General Electric company; Molecular Spectroscopy Section, National Bureau of Standards“The infrared absorption spectra of LiO, $Li_{2}O$ AND $Li_{2}O_{2}$ isolated in solid krypton matrices have been investigated from $300-1000\;cm^{-1}$. The molecules were generated by vaporising solid $Li_{2}O$ in it high temperature effusion cell and trapped in solid krypton matrices at approximately $4^{\circ} K$ and $20^{\circ} K$. The spectrum indicates that $Li_{2}O$ is almost linear and $Li_{2}O_{2}$ is rhombic with an angle of $116^{\circ}$ at Li atom. On the basis of ionic model the equilibrium angle is found to be $118^{\circ}$. The similarity of Lithium Oxide dimer to Lithium Chloride dimer, along with other details will be discussed.
