Infrared spectroscopic characterization of two types of products HSiOH(H2O) <i>n</i> and SiOH(H2O) <i>n</i> ( <i>n</i> = 1–3) in the silicon–water reactions
Abstract
The Si–O–H containing complexes are key interstellar species, but their structural characterization has been proven to be a challenging experimental target because of the difficulty in size selection of neutral clusters in general. Here, two series of products with the chemical formula of SiOnH2n and SiOnH2n−1 (n = 2–4) were prepared via the reactions of laser-ablated silicon atoms with the water molecules and characterized by using size-specific infrared-vacuum ultraviolet (IR–VUV) spectroscopy and quantum chemical calculations. The SiOnH2n and SiOnH2n−1 (n = 2–4) products were identified to have the hydroxysilylene structures HSiOH(H2O)n and the silica hydroxide structures SiOH(H2O)n (n = 1–3), respectively. In particular, the HSiOH(H2O)n and SiOH(H2O)n (n = 2 and 3) complexes were found to have cyclic hydrogen-bonded networks. Two possible pathways for the formation of the observed products have been discussed. This work provides new insights into the astrochemically relevant Si–O–H molecular architectures that are helpful for understanding the formation mechanism of cosmic particle.
