Journal ArticleDOI

The ExoMol database: Molecular line lists for exoplanet and other hot atmospheres

TL;DR: The ExoMol database as mentioned in this paper provides extensive line lists of molecular transitions which are valid over extended temperature ranges, including lifetimes of individual states, temperature-dependent cooling functions, Lande g-factors, partition functions, cross sections, k-coefficients and transition dipoles with phase relations.
Journal ArticleDOI

A room temperature CO2 line list with ab initio computed intensities

TL;DR: In this article, a theoretical model was developed to compute CO2 intensities with uncertainty estimates informed by cross comparing line lists calculated using pairs of potential energy surfaces (PES) and DMSs of similar high quality.
Journal ArticleDOI

Room temperature line lists for CO2 symmetric isotopologues with ab initio computed intensities

TL;DR: In this paper, the authors computed room temperature line lists for six symmetric isotopologues of carbon dioxide, covering the range 0-8000 cm−1, based on variational nuclear motion calculations and on a reliability analysis of the generated line intensities.
Journal ArticleDOI

Field-Induced Diastereomers for Chiral Separation.

TL;DR: A novel approach for the state-specific enantiomeric enrichment and the spatial separation of enantiomers is presented, which utilizes techniques from strong-field laser physics and an optical centrifuge in conjunction with a static electric field to create a chiral field with defined handedness.
Journal ArticleDOI

Highly accurate intensity factors of pure CO2 lines near 2 μm

TL;DR: Line intensities for carbon dioxide are measured with a novel spectroscopic approach, assisted by an optical frequency comb synthesizer for frequency calibration purposes, and are in a very good agreement with recent ab initio predictions.
