Abstract

Last year, at the 68th International Symposium of Molecular Spectroscopy, the rotational spectrum of a complex formed between C$_{2}$H$_{2}$ and AgCCH was presented. The geometry was found to be T-shaped with the silver atom coordinated to the center of the CC bond in acetylene. Evidence for a new complex formed between AgCCH and C$_{6}$H$_{6}$ is now presented in the form of deep-averaged broadband rotational spectra. The spectra are observed only when both C$_{2}$H$_{2}$ and C$_{6}$H$_{6}$ are present in the gas sample. The relative intensities of the observed spectra are consistent with the naturally-occurring abundance ratio of the isotopes of silver. The shift on substitution of $^{107}$Ag for $^{109}$Ag implies a silver atom positioned close to the center of mass. The isotopic shifts observed when C$_{2}$D$_{2}$ is used as a precursor instead of C$_{2}$H$_{2}$ are also consistent with assignment to a complex formed between C$_{6}$H$_{6}$ and AgCCH/D. The geometry of the complex is yet to be precisely established.
