N-like ions atomic data
Extensive multiconfiguration Dirac-Hartree-Fock (MCDHF) calculations and relativistic configuration interaction (RCI) calculations are performed for 272 states of the... -
Line lists of a nitrogen discharge
A discharge of nitrogen gas, as created in a microwave-induced plasma, exhibits a very dense molecular emission line spectrum. Emission spectra of this kind could serve as... -
The mm and sub-mm spectra of 13C-glycolaldehydes
Glycolaldehyde (CH_2_OHCHO) is the simplest sugar and an important intermediate in the path toward forming more complex biologically relevant molecules. Astronomical surveys of... -
