The Atomic Spectroscopy Group at the National Institute of Standards and Technology (NIST) provides the definitive measurements of atomic spectra.

IR spectra reveal the wavelengths absorbed by atomic samples as they interact with infrared light. These spectra can provide detailed information about hyperfine structures: tiny variations in ...

All known features of atomic spectra have been at least semi-quantita-tively explained in terms of the nuclear atom, strictly according to the laws of quantum mechanics.

The US National Institute of Standards and Technology (NIST) is discussing plans to eliminate an entire team responsible for publishing and maintaining critical atomic measurement data in the ...
