Ionization states and cooling efficiencies
We present new computations of the equilibrium and nonequilibrium cooling efficiencies and ionization states for low-density radiatively cooling gas containing the elements H,... -
Transition probabilities for HfII and Hf
Radiative lifetimes from laser-induced fluorescence measurements, accurate to ~+/-5%, are reported for 41 odd-parity levels of HfII (Z=72). The lifetimes are combined with... -
Rotational transitions of Methyl carbamate
The rotational-torsional spectrum of the syn conformer of methyl carbamate [CH_3_OC(:O)NH_2_], an isomer of the essential amino acid glycine [NH_2_CH_2_C(:O)OH], has been... -
Swan system of C2
The C2 Swan system (d ^3^{Pi}g-a ^3^{Pi}u) was observed in emission for the {Delta}v=-3 to {Delta}v=+2 sequences in the 14000-24000cm^-1^ spectral range using a Fourier... -
Multiplet table for neutral helium
This paper combines the precise determination of the energy levels of ^4^HeI from calculations and experiments with theoretical transition probabilities to present multiplet... -
Methyl formate (HCOOCH_3_) observations
We have surveyed a sample of massive star-forming regions located over a range of distances from the Galactic center for methyl formate, HCOOCH_3_, and its isotopologues... -
Calculated spectra for HeH^+^
The wavelength and Einstein A coefficient are calculated for all rotation-vibration transitions of ^4^HeH^+^, ^3^HeH^+^, ^4^He^2^H^+^ and ^3^He^2^H^+^, giving a complete line... -
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...
