Abstract
For cool stellar and substellar objects, atomic lines weaken, and detailed elemental and isotopic abundances are often derived from molecular absorption features. We have embarked on a project to provide molecular line lists by combining experimental observations for line positions with ab initio calculations for line strengths. So far we have results for MgH (A-X and B-X transitions)ab, C₂ (Swan system)cd, CP (A-X transition)f, NH (vibration-rotation bands) and OH (Meinel system)g. This talk will briefly describe the new line lists for the Swan system (d³Π-a³Π) of C₂ and ¹²C¹³C, and the red (A²Π-X²Σ+) and violet (B²Σ+-X²Σ+) systems of CN, ¹³CN and C¹⁵N. Applications to the spectra of carbon-enhanced metal-poor stars, the K-giant Arcturus, the metal-rich open cluster NGC 6791, the Sun and comets will be presented.
