Abstract

The structure of an H2O monolayer bound to atomically smooth hydroxylated amorphous silica is probed under ambient conditions by near-infrared evanescent-wave cavity ring-down absorption spectroscopy. Employing a miniature monolithic optical resonator, we find sharp (10 cm-1) and polarized (>10:1) vibration-combination bands for surface OH and adsorbed H2O, which reveal ordered species in distinct local environments. Indicating first-monolayer uniqueness, the absorption bands for adsorbed H2O show intensity saturation and line narrowing with completion of one monolayer. Formation of the ordered H2O monolayer likely arises from H bonding to a quasicrystalline surface OH network.
