A spectral line list for water isotopologues in the 1100-4100 cm^-1 region for application to CO₂-rich planetary atmospheres

Gamache, Robert R.; Farese, Michaella; Renaud, Candice L.

A line list of transitions for seven isotopologues of water vapor in the 1100-4100 wavenumber range has been constructed for application to atmospheres rich in CO₂. The quantum transitions for H₂¹⁶O, H₂¹⁸O, H₂¹⁷O, HD¹⁶O, HD¹⁸O, and HD¹⁷O a…

CO₂ pressure broadening and shift coefficients for the 2-0 band of ¹²C¹⁶O

Vandaele, A. C.; Vander Auwera, J.; Hashemi, R. +3 more

Fourier transform absorption spectra of the 2-0 band of ¹²C¹⁶O mixed with CO₂ have been recorded at total pressures from 156 to 1212 hPa and at 4 different temperatures between 240 K and 283 K. CO₂ pressure-induced line broadening and line shift coefficients, and the temperature dependence of the former …

Spectroscopic parameters for silacyclopropynylidene, SiC₂, from extensive astronomical observations toward CW Leo (IRC +10216) with the Herschel satellite

Waters, L. B. F. M.; Cernicharo, José; Teyssier, D. +5 more

A molecular line survey has been carried out toward the carbon-rich asymptotic giant branch star CW Leo employing the HIFI instrument on board of the Herschel satellite. Numerous features from 480 GHz to beyond 1100 GHz could be assigned unambiguously to the fairly floppy SiC₂ molecule. However, predictions from laboratory data exhibite…

Broadband analysis techniques for Herschel/HIFI spectral surveys of chemically rich star-forming regions

Bergin, Edwin A.; Lis, Dariusz C.; Phillips, Thomas G. +3 more

The Heterodyne Instrument for the Far Infrared (HIFI) aboard the Herschel Space Observatory has acquired high-resolution broadband molecular spectra of star-forming regions in a wavelength range that is mostly inaccessible from ground-based astronomical observatories. These spectral surveys provide new insight into the chemical composition and phy…
