Abstract
The Atomic Spectroscopy Data Center of the National Institute of Standards and Technology (NIST) is currently compiling spectra and energy levels of the noble gases. A review of the literature has shown that there is no comprehensive experimental description of the infrared spectrum for any of the neutral gases. In response, we have made high-resolutio observations of the spectra of Ne, Kr, and Xe in the region 0.7 to 5.0 m with the 2-m NIST Fourier transform spectrometer. The observations provide precise new wavelengths and relative intensities and resolve questions concerning lines that were previously multiply classified.
