REACTIONS OF LASER ABLATED Be ATOMS WITH H2O: INFRARED SPECTRA OF HOBeOH AND H2O-BeO IN SOLID ARGON..

Products formed by reacting laser ablated Be atoms with H2O included beryllium oxides seen in earlier Be + O2 experiments as well as novel molecules mentioned above. Similar products arise from the formation of BeO in both systems. Once formed BeO may either react with H2O to form HOBeOH or form the H2O-BeO complex. Products were identified by several modes in excellent agreement with DFT calculations and provide interesting comparisons to beryllium oxides such as OBeO and Ar-BeO. HOBeOH is calculated to have an HOOH dihedral angle of 86\circ comparable to H2O2. The molecule also has a linear OBeO subunit whose antisymmetric stretch is observed about 81 cm-1 to the blue of OBeO. Spectra for both species will be presented along with a brief comparison to the oxygen system.
