TLDR
The principles and applications of the quasimolecular treatment of optical and radiative collisions are discussed in this paper, where the main attention is focused on the uniform approximation to the unified Franck-Condon (UFC) line shape of near and far-wings and of rainbow satellites associated with pressure-broadened spectral lines.About:

Calculations of the Far-Wing Line Profiles of Sodium and Potassium in the Atmospheres of Substellar-Mass Objects
TL;DR: In this article, the authors calculate the interaction potentials and the wing line shapes for the dominant Na and K resonance lines in H2 and helium-rich atmospheres in brown dwarfs.
Journal ArticleDOI
A new model for brown dwarf spectra including accurate unified line shape theory for the Na I and K I resonance line profiles
TL;DR: The first brown dwarf atmosphere models based on theoretical calculations of absorption profiles of sodium and potassium perturbed by helium and molecular hydrogen were presented in this article. But the results were limited to the T dwarf SDSS 1624.
Journal ArticleDOI
K–H 2 line shapes for the spectra of cool brown dwarfs
TL;DR: In this paper, it was shown that when the far wing absorption due to alkali atoms in a dense H 2 atmosphere is significant, accurate pressure broadened profiles that are valid at high densities of H 2 should be incorporated into spectral models.
Journal ArticleDOI
A generalized speed-dependent line profile combining soft and hard partially correlated Dicke-narrowing collisions
TL;DR: This paper generalized the combined strong and weak Dicke-narrowed spectral profile of Rautian and Sobel aman for speed-dependent broadening and shifts partially correlated with hard and/or soft velocity-changing collisions.

Self-broadened 12C16O line shapes in the v=2←0 band
J.W Brault,Linda R. Brown,Charles Chackerian,Richard S. Freedman,Adriana Predoi-Cross,A. S. Pine +5 more
TL;DR: In this article, the authors obtained precise intensities, self-broadenings and shifts for the 12 C 16 O v¼ 2 0 band from simultaneous fits of lownoise, high-resolution Fourier transform spectra at pressures from 27 to 80 kPa (200-600 Torr).
