NIST Photoionization of CO2 (ARPES) Database - SRD 119

Data provided by  National Institute of Standards and Technology

CO2 is studied using dispersed synchrotron radiation in the 650 Å and 840 Å spectral region. The vibrationally resolved photoelectron spectra are analyzed to generate relative vibrational transition amplitudes and the angular asymmetry parameters describing the various transitions observed.

NIST MEMS Calculator - SRD 166

Data provided by  National Institute of Standards and Technology

This MEMS Calculator determines the following thin film properties from data taken with an optical interferometer or comparable instrument: a) residual strain from fixed-fixed beams, b) strain gradient from cantilevers, c) step heights or thicknesses from step-height test structures, and d) in-plane lengths or deflections. Then, residual stress and stress gradient calculations can be made after an optical vibrometer or comparable instrument is used to obtain Young's modulus from resonating cantilevers or fixed-fixed beams.
