The NIST bibliographic database on atomic spectral line broadening contains approximately 800 recent references, including numerical data, general information, comments, and review articles.

The atomic weights are available for elements 1 through 111, and isotopic compositions or abundances are given when appropriate.

The Biological Macromolecule Crystallization Database (BMCD) contains crystal data and the crystallization conditions, which have been compiled from literature.

The Community of Science researcher database lets you identify and locate researchers with interests and expertise similar to your own. It contains over 40,000 first-person expertise records. Users may limit retrieval to a particular location or institution and may also add their own record to the database.

Presented in this database are electron-collision cross section data and electron transport coefficients for gases used in the manufacturing of semiconductor devices.

The Elemental Data Index provides access to the holdings of NIST Physics Laboratory online data organized by element. It is intended to simplify the process of retrieving online scientific data for a specific element.

ETDEWEB contains worldwide information in the nuclear, coal, and global climate change areas.

The table of ionization energies in Ground Levels and Ionization Energies for the Neutral Atoms are based on a recent survey of the literature.

The INIS Database, which today contains 2.7 million bibliographic records; it is accessible by subscription only and has currently 1.3 million authorized users.

INIS is the world’s largest database of scientific and technical literature on a wide range of subjects from nuclear engineering, safeguards and non-proliferation to applications in agriculture, health and industry.

Database of some of the leading engineering reference handbooks, databases, and conference proceedings.

Data for free radical processes involving primary radicals from water, inorganic radicals and carbon-centered radicals in solution, and singlet oxygen and organic peroxyl radicals in various solvents.

The NIST Chemical Kinetics Database includes all reported kinetics results for thermal gas-phase chemical reactions.
