NIST Polycyclic Aromatic Hydrocarbon Structure Index - SRD 204
Data provided by National Institute of Standards and Technology
This website was designed to serve two purposes: 1) serve as a modern replacement for the original web site serving the content of NIST Special Publication 922: Polycyclic Aromatic Hydrocarbon Structure Index 2) serve thermochemical data derived in the publication 'First Principles Prediction of Enthalpies of Formation for Polycyclic Aromatic Hydrocarbons and Derivatives,' Thomas C. Allison and Donald R. Burgess Jr., manuscript in preparation.

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.

NIST Libraries of Peptide Fragmentation Mass Spectra Database - SRD 1c
Data provided by National Institute of Standards and Technology
NIST peptide libraries are comprehensive, annotated mass spectral reference collections from various organisms and proteins useful for the rapid matching and identification of acquired MS/MS spectra. Spectra were produced by tandem mass spectrometers using liquid chromatographic separations followed by electrospray ionization. Unlike the NIST small molecule electron ionization library which contains one spectrum per molecular structure, there are several different modes of fragmentation (ion trap and ?beam-type?

NIST Database of Cross Sections for Inner-Shell Ionization by Electron or Positron Impact - SRD 164
Data provided by National Institute of Standards and Technology
The NIST Database of Cross Sections for Inner-Shell Ionization by Electron or Positron Impact provides cross sections for ionization of the K shell and of the L and M subshells of neutral atoms of the elements, from hydrogen to einsteinium, by electrons or positrons, for projectile energies from the ionization threshold to 1 GeV. These cross sections were calculated from a combination of the relativistic distorted-wave and the plane-wave Born approximations.
