Spin-orbit and spin-rotation coupling in doublet states of diatomic molecules
John M. Brown,James K.G. Watson +1 more
TL;DR: The spin-rotation interaction and the centrifugal correction to the spin-orbit coupling make indistinguishable contributions to the energy levels of a diatomic molecule in a multiplet state with Λ ≠ 0.

OH− and OD− threshold photodetachment
TL;DR: In this paper, threshold photodetachment cross sections for the negative ion at photon energies close to their electron binding energies have been obtained using a crossed tunable laser−negative ion beam apparatus at a resolution of 25 μeV.

Analysis of perturbations in the A2Π-X2Σ+ “Red” system of CN
TL;DR: In this paper, the deperturbed vibration-rotation constants of the A 2 Π and X 2 Σ + (v = 0 to 8) states of CN were obtained using a weighted, nonlinear least squares fitting routine.

Fourier spectroscopy of the OD infrared spectrum. Merge of electronic, vibration-rotation, and microwave spectroscopic data
TL;DR: In this article, the OD infrared spectrum, emitted in a flame of deuterium and oxygen, has been recorded for the first time in the 2-μm spectral range with a Fourier Transform spectrometer.
Journal ArticleDOI
Radiative lifetimes and dipole moments of the A 2Σ+, B 2Σ+, and C 2Σ+ states of OH
TL;DR: In this article, the eigenfunctions of the X 2Pi and excited A 2Sigma(+), B 2 Sigma(+) and C 2 Sigmoid(+) states of the ground state were described and the radiative lifetimes derived from calculation of the bound-bound and bound-free vibrational band transition probabilities were compared with measured values.

On σ -Type Doubling and Electron Spin in the Spectra of Diatomic Molecules
TL;DR: In this paper, it was shown that the rotational distortion due to molecular rotation causes the width of a spin multiplet to depend on the position of the spin axis relative to the axis of the figure.

A Direct Approach for the Reduction of Diatomic Spectra to Molecular Constants for the Construction of RKR Potentials
TL;DR: In this article, a nonlinear fitting procedure is presented that employs all measured line positions and iteratively compares their values with those calculated from numerically diagonalized model Hamiltonians with adjustable molecular constants.

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.
