Abstract
“Studies have been made of the spectra of simple inorganic molecules and of complex ions in solution in ionic solids. Solutions are prepared by quenching a melt of the solvent to which has been added a small amount ($<1$%) of solute. The alkali halides have been used most frequently as solvents, since the resultant solution may be pressed into a window for convenient examination. By the technique of solution, near neighbor interactions are minimized, and sharpened, more intense spectra are observed. These represent equilibria frozen at the melting point of the solvent. In this manner the spectra of monomeric $SeO_{2}$ and $TeO_{2}$ which exist as chain polymers in their solid phases, have been studied and assigned. The solution spectra of certain complex ions will be discussed, including frequency shifts and other solid state interactions which are observed.”
