摘要：

The weakly bound complexes Al-(H2O) and Al-(D2O) 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-H2O: omega(e)(+) = 327.5 cm(-1)). The origin energy, Al atom ionization potential and the known Al+-(H2O) bond energy produce a neutral Al-(H2O) 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. (C) 1999 Elsevier Science B.V. All rights reserved.
