This paper describes the contents of 2016 edition HITRAN molecular spectroscopic compilation. The new replaces previous 2012 and its updates during intervening years. absorption compilation is composed five major components: traditional line-by-line parameters required for high-resolution radiative-transfer codes, infrared cross-sections molecules not yet amenable to representation in a form, collision-induced data, aerosol indices refraction, general tables such as partition sums that apply...
The HITRAN database is a compilation of molecular spectroscopic parameters. It was established in the early 1970s and used by various computer codes to predict simulate transmission emission light gaseous media (with an emphasis on terrestrial planetary atmospheres). composed five major components: line-by-line parameters required for high-resolution radiative-transfer codes, experimental infrared absorption cross-sections (for molecules where it not yet feasible representation form),...
Extensive rovibrational line lists were computed for nine isotopologues of the CO molecule, namely, 12C16O, 12C17O, 12C18O, 13C16O, 13C17O, 13C18O, 14C16O, 14C17O, and 14C18O in ground electronic state with v ⩽ 41, Δv 11, J 150. The intensity position calculations carried out using a newly determined piece-wise dipole moment function (DMF) conjunction wavefunctions calculated from an experimentally potential energy Coxon & Hajigeorgiou. A direct-fit method that simultaneously fits all...
This is the third of a series articles reporting critically evaluated rotational–vibrational line positions, transition intensities, and energy levels, with associated reviewed labels uncertainties, for all main isotopologues water. paper presents experimental experimental-quality validated transitions most abundant isotopologue water, H216O. The latest version MARVEL (Measured Active Rotational–Vibrational Energy Levels) line-inversion procedure used to determine rovibrational levels...
The report of an IUPAC Task Group, formed in 2011 on "Intensities and line shapes high-resolution spectra water isotopologues from experiment theory" (Project No. 2011-022-2-100), profiles isolated rotational-vibrational transitions perturbed by neutral gas-phase molecules is presented. well-documented inadequacies the Voigt profile (VP), used almost universally databases radiative-transfer codes, to represent pressure effects Doppler broadening vibrational-rotational pure rotational...
The ultimate sensitivity performances obtained with a continuous wave-cavity ring down spectroscopy setup in the near infrared are investigated. At fixed frequency, noise of photodetector is found to be main limitation and best limit detection (about 10−11 cm−1) reached after 10 s averaging. We show that long term baseline fluctuations can efficiently averaged over several days allowing us reach as low 5 × 10−13 cm−1. achieved illustrated on narrow spectral intervals where weakest lines...
Information on the vibrational energy states in acetylene (12C2H2, C212D2, and C213H2) is gathered: spectroscopic constants (vibrational frequencies anharmonicities, vibration-rotation interaction parameters), observed complete sets of predicted energies principal rotational Bv for C212H2, C213H2 up to 15000, 10000, 12000 cm−1, respectively. Statistical parameters (partition functions integrated number states) deduced from these data are provided three isotopomers. The equilibrium...

Five very weak transitions-O(2), O(3), O(4), O(5) and Q(5)-of the first overtone band of H(2) are measured by high sensitivity CW-Cavity Ring Down Spectroscopy (CRDS) between 6900 7920 cm(-1). The noise equivalent absorption recordings is on order α(min)≈ 5 × 10(-11) cm(-1) allowing for detection transition with an intensity 1.1 10(-30) cm per molecule, smallest value so far line. A Galatry profile was used to reproduce line shape derive strengths. pressure shift O(2) O(3) lines accurately...
