HITEMP, the high-temperature molecular spectroscopic database

TLDR
In this paper, a new molecular spectroscopic database for high-temperature modeling of the spectra of molecules in the gas phase is described, called HITEMP, which is analogous to the HITRAN database but encompasses many more bands and transitions than HitRAN for the absorbers H2O, CO2, CO, NO and OH.
Abstract
A new molecular spectroscopic database for high-temperature modeling of the spectra of molecules in the gas phase is described. This database, called HITEMP, is analogous to the HITRAN database but encompasses many more bands and transitions than HITRAN for the absorbers H2O, CO2, CO, NO, and OH. HITEMP provides users with a powerful tool for a great many applications: astrophysics, planetary and stellar atmospheres, industrial processes, surveillance, non-local thermodynamic equilibrium problems, and investigating molecular interactions, to name a few. The sources and implementation of the spectroscopic parameters incorporated into HITEMP are discussed.

Molecular spectroscopy and dynamics: A polyad-based perspective

TL;DR: The efficiency and insight of global, polyad-based modeling in overtone spectroscopy and dynamics is demonstrated and the dynamical implications of polyad Hamiltonians include classical bifurcations that lead to the birth of new vibrational modes and intramolecular vibrational-rotational energy redistribution over multiple timescales.

Can increased atmospheric CO2 levels trigger a runaway greenhouse

TL;DR: It is argued that Earth's real climate is probably stable given more realistic assumptions, although 3-D climate models will be required to verify this result.

The HITRAN 2008 molecular spectroscopic database

TL;DR: The new HITRAN is greatly extended in terms of accuracy, spectral coverage, additional absorption phenomena, added line-shape formalisms, and validity, and molecules, isotopologues, and perturbing gases have been added that address the issues of atmospheres beyond the Earth.

The hitran molecular database: editions of 1991 and 1992

TL;DR: The HITRAN molecular absorption database as mentioned in this paper contains line parameters for 31 species and their isotopomers that are significant for terrestrial atmospheric studies, including chlorofluorocarbons and other molecular species that are not amenable to line-by-line representation.

The determination of an accurate isotope dependent potential energy surface for water from extensive ab initio calculations and experimental data

TL;DR: In this article, a high quality ab initio potential energy surface (PES) and dipole moment function (DPM) for water has been determined and an adjusted PES is empirically adjusted to improve the agreement between the computed line positions and those from the HITRAN 92 data base with J⩽5 for H216O.

A high-accuracy computed water line list

TL;DR: The most complete water line list in existence, comprising over 500 million transitions (65 per cent more than any other list) and also the most accurate (over 90 per cent of all known experimental energy levels are within 0.3 cm −1 of the BT2 values) is presented in this article.
