“…The resulting molecular cross section for water was found to be r ¼ 1.4 Â 10 À16 cm/molecule at 16°C [58] and is assumed to be the same at 10°C. The surface density of adsorbed water, S H 2 O , is then obtained from a modified Beer-Lambert relationship [63],…”

“…1. With the facets' orientation and the substrate's reflectivity properly considered [24], we estimate that nearly 40% of C(100) and 10% of the C(110) surface in Fig. 2 are covered with the newly formed ͕111͖-oriented facets.…”

Etching of natural diamonds by atomic hydrogen has been investigated on C(100), C(110), and C(111) single crystal surfaces. Infrared absorption spectroscopy and low-energy electron diffraction provide direct evidence for an etching anisotropy at 1100 K. The results indicate that, in the presence of atomic hydrogen, ͕111͖-oriented facet formation irreversibly occurs on both C(110) and C(100), whereas C(111) remains intact. The finding has important implications for chemical vapor deposition diamond synthesis and H-plasma surface polishing. [S0031-9007(97)03064-0]

“…From FTIR data, this value is estimated to be 0.13-0.16 D. 42,52 Equations ͑2͒ and ͑4͒ are then used to calculate lifetimes with this range of dipole moment values. 43 Lifetimes in the range of 12-18 ps are obtained for r s ϭ3 a.u.…”

The lifetimes on Pt͑111͒ and Au are potential dependent and range from 3 to 8 ps and 10 to 19 ps, respectively, with the longer lifetimes occurring at more positive potentials. Results for the Ag surface show solvent dependent lifetimes of Ϸ28 ps in a 0.1 M solution of NaClO 4 in H 2 O and Ϸ60 ps when the solvent is changed to D 2 O. The results on all of these metals are surprising because of the comparatively short ͑1.5-3.0 ps͒ lifetimes predicted and measured for isoelectronic CO. The lifetimes on Ag are remarkable because of their similarity to those of freely-solvated CN Ϫ ions. We discuss our results in the context of a charge transfer to the substrate and also consider an image dipole mechanism.
