 Title: ZEKE-PFI SPECTROSCOPY OF THE $Al-(H_{2}O)$ AND $Al-(D_{2}O)$ COMPLEXES. Creators: Agreiter, J. K.; Knight, A. M.; Grieves, G. A.; Duncan, M. A. Issue Date: 2000 Publisher: Ohio State University Abstract: The weakly bound complexes $Al-(H_{2}O)$ and $Al-(D_{2}O)$ are prepared with pulsed laser vaporization and studied with single-photon ZEKE-PFI spectroscopy. The spectra consist of progressions in the Al-water stretch in the ground state of the corresponding cations $(Al-(H_{2}O): \omega^{+}_{e}=327.5 cm^{-1})$. The origin energy, Al atom ionization potential and the known $Al^{+}-(H_{2}O)$ bond energy produce a neutral $Al-(H_{2}O)$ bond energy of $D_{0}=1440 cm^{-1}$. Partially resolved rotational structure suggests that the cation complexes have $C_{2v}$ structures, while the neutrals are non-planar. The neutral structure and energetics are consistent with a metal-water coordinate-covalent bond, which has been predicted by theory.
