Addition of the line list for carbon disulfide to the HITRAN database: line positions, intensities, and half-widths of the 12C32S2, 32S12C34S, 32S12C33S, and 13C32S2 isotopologues

Total internal partition sums for the HITRAN2020 database

“…The rotational constants for all four isotopologues are from Karlovets et al [153] and were used to compute the partition sums via McDowell's linear molecule analytical formula. The Gv values are also from Karlovets et al [153] for the four isotopologues.…”

“…The rotational constants for all four isotopologues are from Karlovets et al [153] and were used to compute the partition sums via McDowell's linear molecule analytical formula. The Gv values are also from Karlovets et al [153] for the four isotopologues. Note however, the Gv(01 1 0) value for 32 S 12 C 33 S2 was estimated from the average ratio Gv(02 0 0)/ Gv(01 1 0)= 0.494, from the other three isotopologues and the Gv(02 0 0) value for 32 S 12 C 33 S2.…”

Accurate Infrared Line Lists for 20 Isotopologues of CS2 at Room Temperature

“…However, until recently it was not available in any popular astronomical or atmospheric high-resolution IR databases, and only medium-resolution spectra in the range of 600-6400 cm −1 existed in the PNNL spectroscopic database of experimental cross sections (Johnson et al 2004;Sharpe et al 2004). To address this issue, the 2020 version of the HITRAN database (Karlovets et al 2021;Gordon et al 2022) was expanded to include the four most abundant isotopologues of CS 2 based on a global semiempirical model. Even more recently, a new global effective Hamiltonian model (Tashkun 2022) was published for 12 C 32 S 2 , the main isotopologue.…”

“…After 2000, CS 2 high-resolution IR measurements (Blanquet et al 2003(Blanquet et al , 2006de Ghellinck d'Elseghem Vaernewijck et al 2012) came with more line-broadening coefficient studies (Misago et al 2007(Misago et al , 2009Kongolo Tshikala et al 2012. These valuable experimental data were collected in Karlovets et al (2021) for HITRAN2020 and in Tashkun's effective Hamiltonian model (Tashkun 2022).…”

“…The CS 2 list in HITRAN2020 included more than 83,000 transitions of the four most abundant isotopologues: 12 C 32 S 2 , 32 S 12 C 34 S, 32 S 12 C 33 S, and 13 C 32 S 2 , which were generated (see Karlovets et al 2021) in the range of 0-6470 cm −1 and J up to 150, using the PGOPHER program to fit thousands of measured line positions and transition dipole moments. Due to the fact that CS 2 is often used as a calibration gas, the line positions of CS 2 have been measured in many works with very high precision, and therefore the effective model is based on a large subset of high-quality data (see, for instance, Wells et al 1988 andKarlovets et al 2020).…”
