ESR Spectroscopy and Chemical Bonding in CdCN and HgCN Molecules
Knight, L. B. ESR Spectroscopy and Chemical Bonding in CdCN and HgCN Molecules. J. Chem. Phys. 1972, 56, 6044-6044.
The radical molecules CdCN and HgCN were trapped in rare gas matrices at 4Â°K and investigated via ESRspectroscopy. The gtensors and hyperfine structure constants (hfs) for interaction with 111Cd, 113Cd, 199Hg, and 201Hg were determined. These measurements indicate that CdCN and HgCN have 2Î£ ground electronic states and predict the presence of 2II r excited states near 2700 Ã…. The ionicity of these molecules are discussed based on an (ns)2 S M+ limiting model and compared with previous results obtained for the more covalent CdH and HgH molecules.
