The NIST Physics
Program produces the most comprehensive set of reliable physical reference
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 4000 compounds.
The WebBook also contains constants of diatomic molecules.
The SRD Group
has also produced several important compilations of molecular data.
