Chemistry & Chemical Engineering (CCE): Spectra Sources

Periodic table format for neutral atoms

Wavelengths, intensities, and spectrum assignments for neutral and singly-ionized atoms of all elements hydrogen through einsteinium (Z = 1-99).

Transition probabilities, spectral line broadening and energy levels and wavelengths.

1. Spectral lines and associated energy levels displayed in wavelength order with all selected spectra intermixed or in multiplet order. Transition probabilities for the lines are also displayed where available. 2. Energy levels of a particular atom or ion displayed in order of energy above the ground state.

"References to data retreived from a database should be cited like a web site and include the CAS Registry Number (RN) or chemical name and the date the database was accessed. If the data are calculated data, also cite the software used for the calculation."

Contains UV spectra for ~700 compounds

A majority of spectra are taken from original scientific papers. Some are taken from published collections.

SDBS is an integrated spectral database system for organic compounds,which includes 6 different types of spectra under a directory of the compounds. The six spectra are as follows, an electron impact Mass spectrum (EI-MS), a Fourier transform infrared spectrum (FT-IR), a 1H nuclear magnetic resonance (NMR) spectrum, a 13C NMR spectrum, a laser Raman spectrum, and an electron spin resonance (ESR) spectrum.
