Absolute surface coverage measurement using a vibrational overtone.

Determination of absolute surface coverage with sub-monolayer sensitivity is demonstrated using evanescent-wave cavity ring-down spectroscopy (EW-CRDS) and conventional CRDS by employing conservation of the absolute integrated absorption intensity between gas and adsorbed phases. The first C-H stretching overtones of trichloroethylene (TCE), cis-dichloroethylene, and trans-dichloroethylene are ...

Absolute measurement of surface roughness.

In an interferometer which uses a reference surface, the measured surface heights correspond to the difference between the test and reference surfaces. To accurately determine the rms roughness of supersmooth surfaces, the effects of the reference surface roughness need to be removed. One technique for doing this involves averaging a number of uncorrelated measurements of a mirror to generate a...

Direct translation-to-vibrational energy transfer of HCl on gold: Measurement of absolute vibrational excitation probabilities

Vibrational excitation of HCl molecules (m = 0 ! 1) has been observed when HCl molecular beams at energies of 0.59–1.37 eV are scattered from a Au(111) surface at low surface temperature (Ts = 273 K). The incident and scattered HCl is probed state-selectively using 2 + 1 REMPI. The vibrational excitation probability depends strongly on incidence kinetic energy, Ei, exhibiting a threshold near E...

Measurement of Vibrational Motions using a Three-Facet Mirror

A new measurement method to measure vibrational motions of objects is presented. The original principle is similar to the previous work that utilized a 3-facet mirror to obtain three dimensional positions and orientations of rigid bodies. While the previous work was presented for only stationary objects, in this paper, we newly investigate the feasibility of this method for dynamic applications...

Chromophore dependence of intramolecular vibrational relaxation: Si–H stretch second overtone versus C–H stretch first overtone in methylsilane

The intramolecular vibrational relaxation ~IVR! of an excited Si–H stretch ~second overtone! and C–H stretch ~first overtone! in methylsilane has been examined by eigenstate resolved infrared spectroscopy. The experiment probes a molecular beam produced in a supersonic expansion, excited by a laser in a power buildup cavity, and detected by a liquid helium cooled silicon bolometer. The Si–H str...
