Abstract

The 11 electron CBC radical has been generated by the pulsed laservaporization of elemental carbon-€“boron mixtures and trapped in neon, argon and krypton matrices for detailed electron spin resonance(ESR) studies. Extensive comparisons of the experimental nuclear hyperfineAtenors for carbon and boron were made with a variety of ab initio computational results that involved different levels of theory and basis sets. These new ESR results agree with recent vibrational studies of CBC that show it to have a nonlinear symmetric geometry with a 2 A 1 electronic ground state. These ESR results provide a description of the singly occupied molecular orbital. The spin density resides primarily on boron in 2s and 2p z orbitals, however a complete resolution of the 13C hyperfine structure does show that approximately 20% resides on the carbon atoms.
