Atomic
and Molecular Physics
The NIST Atomic Physics
Program produces the most comprehensive set of reliable atomic data available
anywhere.
The NIST collection
of atomic energy levels, transition probabilities, and collision data
is widely used by groups for characterizing and modeling all types of
gaseous systems, including plasmas, planetary atmospheres, and astrophysical
media, and for health physics applications. Databases and publications
make these data easy to find and easy to use. The physics online databases
have grown into an extensive listing. The NIST Chemistry WebBook now contains
electronic and vibrational spectra for over 5000 compounds. The WebBook
also contains constants of diatomic molecules.
The SRD Program has
also produced several important compilations of molecular data.
