Laboratory Spectroscopy and Herschel and APEX Observations of Light Hydride Species

Observations of CH+, J = 1 − 0 and 2 − 1 near 0.835 and 1.67 THz with Herschel/HIFI and of 13CH+, J = 1 − 0 near 0.830 THz with APEX revealed their rest frequencies to be higher than the accepted values by 21 and 30 km s-1, respectively. Very recent laboratory measurements of the J = 1 − 0 transition frequencies of CH+, 13CH+ and CD+ and fits to these as well as electronic spectral data resolved the descrepancies. The laboratory spectroscopic situation will be reviewed for selected cationic light hydride species.
