Infrared Spectroscopy of Hydrogen and Water on Diamond (100)

Abstract

The absorption of deuterium and water on diamond (100) has been investigated by infrared multiple-internal-reflection spectroscopy using a natural type IIa diamond internal reflection element. Evidence was seen for both monohydride surface species (CD deformation mode at 901/cm) and dihydride species (CD2 deformation mode at 1125/cm). Following exposure to water at elevated temperature, infrared modes were detected at 1280, 1200, 1125, 1080, and 720/cm, and are assigned to ether (C-O-C), hydroxyl (-OH), and carbonyl (>C=O) modes. The substantial observed reactivity of diamond with water indicates a potentially important role for surface hydroxyl and oxide species in diamond growth.
