NIST Atomic Spectra Database

Contains data for radiative transitions and energy levels in atoms and atomic ions. Data are included for observed transitions of 99 elements and energy levels of 52 elements. ASD contains data on about 900 spectra from about 1 Å to 200 μm, with about 70,000 energy levels and 91,000 lines, 40,000 of which have transition probabilities listed. The most current NIST-evaluated data associated with each transition are integrated under a single listing.

Biological Macromolecule Crystallization Database (BMCD)

The Biological Macromolecule Crystallization Database (BMCD) contains molecule, crystal and crystallization data for macromolecules for which diffraction quality crystals have been obtained. These include proteins and nucleic acids, various complexes, and viruses. The current release includes 43,406 crystal entries, up from 14,372 in the previous release. The new data have been extracted from PDB REMARK 280 records. The data have been converted into scientific format (from aggregate text string to individual, numeric data) with error checking and standardization of chemical names.
