  • H13CN/HN13C linelist

    A linelist of vibration-rotation transitions for ^13^C substituted HCN is presented. The line list is constructed using known experimental levels where available, calculated...
  • Linelist of HCN and HNC

    We build an accurate database of 5200 HCN and HNC rotation-vibration energy levels, determined from existing laboratory data. 20000 energy levels in the Harris et al.,...
  • Millimeter-wave spectrum of 2-propanimine

    Up to date, only six imines have been detected in the interstellar medium. The 3-carbon imine, 2-propanimine ((CH_3_)_2_C=NH), is predicted to be the structural isomer with the...
  • ExoMol molecular line lists. XLIV. SiO

    A new silicon monoxide (^28^Si^16^O) line list covering infrared, visible and ultraviolet regions called SiOUVenIR is presented. This line list extends the infrared EBJT ExoMol...
  • ExoMol Molecular linelists. XXXIII. TiO

    Accurate line lists are crucial for correctly modelling a variety of astrophysical phenomena, including stellar photospheres and the atmospheres of extra-solar planets. This set...
  • ExoMol line lists. Spectra of SH and NS

    Line lists for sulphur containing molecules SH (the mercapto radical) and NS are computed as part of the ExoMol project. These line lists consider transitions within the ground...
  • ExoMol line lists. XXIV. SiH

    SiH has long been observed in the spectrum of our Sun and other cool stars. Computed line lists SiGHTLY for the main isotopologues of silicon monohydride, ^28^SiH, ^29^SiH,...
  • ExoMol line lists. PO and PS spectra

    Comprehensive line lists for phosphorus monoxide (PO) and phosphorus monosulphide (PS) in their X2Pi electronic ground state are presented. The line lists are based on new ab...
  • ExoMol line lists for ^28^SiH_4_

    A variationally computed ^28^SiH_4_ rotation-vibration line list applicable for temperatures up to T=1200K is presented. The line list, called OY2T, considers transitions with...
  • ExoMol Line List XXI: Nitric Oxide (NO)

    Line lists for the ground electronic ground state for the parent isotopologue of nitric oxide and five other major isotopologues are presented. The line lists are constructed...
  • ExoMol molecular line lists for H3+

    H_3_^+^ is a ubiquitous and important astronomical species whose spectrum has been observed in the interstellar medium, planets and tentatively in the remnants of supernova...
  • ExoMol line list for H_2_^18^O and H_2_^17^O

    Hot line lists for two isotopologues of water, H_2_^18^O and H_2_^17^O, are presented. The calculations employ newly constructed potential energy surfaces (PES), which take...
  • ExoMol. XVII: SO3

    Sulphur trioxide (SO_3_) is a trace species in the atmospheres of the Earth and Venus, as well as being an industrial product and an environmental pollutant. A variational line...
  • ExoMol line lists for SO2

    Sulphur dioxide is well-known in the atmospheres of planets and satellites, where its presence is often associated with volcanism, and in circumstellar envelopes of young and...
  • H_3_O^+^ and D_3_O^+^ rotational transitions

    The mass sensitivity of the vibration-rotation-inversion transitions of H_3_^16^O^+^, H_3_^18^O^+^, and D_3_^16^O^+^ is investigated variationally using the nuclear motion...
  • Stark broadening of XeVIII spectral lines

    Stark broadening parameters have been calculated for 60 spectral lines of XeVIII, for broadening by electron, proton, and HeIII impacts. For calculations, the semiclassical...
  • ExoMol line lists for NaH and NaD

    Accurate and complete rotational-vibrational and rotational-vibrational- electronic line lists are calculated for sodium hydride: both NaH and NaD isotopologue are considered....
  • Formamide detection with ASAI-IRAM

    Formamide (NH_2_CHO) has been proposed as a pre-biotic precursor with a key role in the emergence of life on Earth. While this molecule has been observed in space, most of its...
  • Hydrogen Lyman and Balmer line profiles

    We present new calculations of unified line profiles for hydrogen perturbed by collisions with protons. We report on new calculations of the potential energies and dipole...
  • Line lists

    Knowledge of the elemental abundances of symbiotic giants is essential to address the role of chemical composition in the evolution of symbiotic binaries, to map their parent...
