Infrared Emission Spectroscopy and Molecular Astronomy

Résumé : Our recent laboratory and astronomical work on a variety of molecules including VCl, CrH, SO, BeH2, hot CH4, and hot H2O as well as on hydrogenated amorphous carbon thin films will be presented. The main theme of the talk is the interaction of laboratory spectroscopy and observational infrared and near infrared astronomy. Laboratory infrared emission spectra were recorded with a Fourier transform spectrometer. A number of molecular sources were utilized including a new source that combines a high temperature furnace with an electrical discharge. Astronomical spectra of sun spots, cool dwarf stars, brown dwarfs, protoplanetary nebulae and the Jovian moon Io were recorded with a variety of telescopes and spectrographs. For example, high resolution infrared spectra of brown dwarfs were just recorded with the Phoenix instrument at the 8 meter Gemini South telescope in Chile.
