Pentad: The same TheoReTS line list has also been used to replace the previous pentad data, after detailed comparisons to high resolution spectra.

Dyad: Line positions and intensities of the ν 2 and ν 3 bands of the dyad remain unchanged but have been supplemented with a number of hot/combination bands from an updated empirically-corrected ab initio line list provided by the TheoReTS team (M.

The phosphine (PH 3) line list has received a significant update, which encompasses all spectral regions in HITRAN. The first-order line-mixing coefficients were calculated based on the exponential power gap law (EPG) formalism and are now provided for every transition in HITRAN. , and the air- and self -shifts were calculated based on the method proposed by Hartmann. The Voigt self broadened half widths were fitted using the data from Werwein et al. The temperature exponents of the air broadening were extrapolated as well using the Pade approximation fit to the data from. The air-broadening parameters from NIST were fit with Pade approximates and the results have been applied for the air half widths (for both the VP and SDV), and the speed dependence of air widths (except for the ν 3 band).

The line-shape parameters for lines of N 2O in other bands:The line shape parameters have been revised (or added) for Voigt (VP) and SDV profiles, which have been treated separately. Note that these parameters were already present under Hartmann-Tran profile parametrization in HITRAN2016.

Ν 3 band : The measurements from were used for updating the speed-dependent Voigt (SDV) parameter group such as air-broadening, air- speed dependence of width, air-shift, and the first-order line-mixing parameter for the measured transitions in this band. Also additional transitions up to J''= 91 were added for these bands. (2003), and the H 2, He and CO 2 broadening parameters (described by Wilzewski et al., 2016) have been extended to all new transitions.Ĥν 1+2ν 2 and 5ν 1 bands: The line intensities for these bands have been replaced by the recent NIST CRDS measurements Adkins et al. Each state is now identified by the following: V 1, V 2, V 3, V 4, V 5, l 4, l 5, +/-, u/ g (where V i are the vibrational normal mode quantum numbers).įinally, the air- and self-broadening parameters have been made consistent using the function provided by Jacquemart et al. The C 2H 2 format has been updated for all lines to include both bending angular momentum quantum numbers (i.e, l 4 and l 5).

In addition, eight hot bands have been added for the ΔP=6 region (near 3900 cm -1) using the global model developed by Lyulin & Perevalov (2016).Īs many more C 2H 2 bands have been added to HITRAN, it has become necessary to update the vibrational quantum number format to avoid degeneracy and allow unique identifications. Numerous bands have been added to HITRAN for 12C 2H 2 in the 13.6 μm region (ΔP=1) from Jacquemart et al. In addition to the updates introduced in July 2020, further additions and improvements have been made to the line list of C 2H 2.

When citing the database it is recommended to indicate if an updated version of the HITRAN2016 edition was used. Updates, improvements, and corrections to the edition are posted in the "Database Updates" panel located on the home page of the HITRAN web-site. => Note that we are constantly making ongoing improvements and additions to many molecular bands.
