INFRARED SPECTROSCOPIC STUDIES OF MATRIX ISOLATED COMPLEXES OF CIF WITH SELECTED LEWIS BASES

Author Institution: Department of Chemistry, University of CincinnatiThe matrix isolation technique has been successfully used to stabilize complexes formed between CIF and a variety of Lewis bases. Twin jet deposition was employed in these studies, and argon and nitrogen were used as the matrix materials. For those Lewis bases which contained an oxygen atom, product bands were located near parent bands which had been assigned to vibrations involving the oxygen atom. These results indicate that the CIF molecule is bound to the oxygen atom in the complex. Perturbed CIF vibrations were shifted to lower energies up to $100 cm^{-1}$ and often revealed $FCl^{35}/FCl^{37}$ isotopic splitting. Studies are underway with nitrogen-containing Lewis bases, and will be discussed
