Abstract

Electronic spectra of zinc cyclopentadienide $(ZnC_{5}H_{5})$ and cadmium cyclopentadienide $(CdC_{5}H_{5})$ will be presented. Preparation of these radicals, neither of which has been observed previously in the gas phase, was achieved using a laser vaporization/photolysis technique. The $\tilde{A}-\bar{X}$ and $\bar{B}-\bar{X}$ electronic transitions of both of these molecules have been recorded. Assignments of the symmetries of the low-lying electronic states of $ZnC_{3}H_{5}$ and $CdC_{5}H_{5}$ will be given and an analysis of the vibrational structure observed in their spectra will be discussed.""
