Rotational Energy Levels of a Linear Triatomic Molecule in a 2Π Electronic State
TL;DR: In this article, the rotational energy levels of a linear triatomic molecule in a 2Π electronic state were derived for the spin orbit interaction and a vibronic Renner interaction, and the results were valid when both interactions are small compared to the bending vibrational frequency.

Infrared Spectra and the Structures and Thermodynamics of Gaseous LiO, Li2O, and Li2O2
TL;DR: In this article, the vapor above heated lithium oxide (Li2O) has been investigated mass spectrometrically and by infrared matrix-isolation spectroscopy and the vapor composition and Knudsen effusion rates were measured as functions of temperature, and the matrix spectra of the principal lithium oxide species were identified and analyzed for different isotopic abundances.

Long Optical Paths of Large Aperture
TL;DR: In this article, an absorption cell is described, in which the light traverses a small volume a large and arbitrarily variable number of times, and the angular aperture of the mirrors is not occulted either on or off the optical axis, and can be used for observing spectra that are very weak, or that belong to high boiling point compounds or to compounds obtainable only in very low concentrations.

The Dispersion of Standard Air
TL;DR: By combining Barrell and Sears' measurements in the visible and Koch's and Traub's in the ultraviolet, a dispersion formula for standard air has been derived, viz., (n−1)108=6432.8+2 949 810(146−σ2)−1+25 540(41−σ 2)− 1,σ being vacuum wave number in μ−1, which should satisfy all needs of precision spectroscopy, in particular for converting wavelengths in air into vacuum values.

Λ-Type Doubling and Electron Configurations in Diatomic Molecules
TL;DR: In this article, Van Vleck's equations for a wide variety of data on many molecules, including data on several intermediate coupling cases between $a$ and $b$, are restated in convenient form for application to empirical data, explicit equations being given for each component separately in a $\ensuremath{\Lambda}$-type or spin doublet.

The Renner effect and spin-orbit coupling
TL;DR: In this article, the Renner theory of vibrational-electronic interaction in linear triatomic molecules in Π electronic states is extended to take account of coupling between an odd electron spin and the electron orbital angular momentum.
