Matrix-isolation studies on Group 3 trihalides. Part I. Vibrational spectra and molecular shapes of monomeric trichlorides of aluminium, gallium, and indium

Abstract

High-resolution Raman and i.r. studies have been made on monomeric AlCl3, GaCl3, and InCl3 isolated in argon matrices at low temperatures. All the in-plane fundamentals of these molecules are located, and it is shown that the isotope frequency and intensity patterns observed under high resolution may be interpreted using a relatively simple model which appears to have wide application. On the basis of these experiments, planar geometries are derived for all three molecules, and it is conclusively demonstrated that an earlier matrix-isolation study of AlCl3 is based on incorrect band assignments.
