The Atomic Spectroscopic Data Center at NIST provides the most comprehensive
collection of atomic spectroscopy data in the world. We monitor scientific
literature and maintain bibliographic databases of all papers containing
spectroscopic data. By evaluating and compiling data on energy levels,
transition probabilities, wavelengths, and lifetimes, we make it possible for
researchers around the world to access these data quickly and efficiently.
Our work is distributed though critically evaluated publications, stand-alone
databases for PCs, and the World Wide Web. |
