The pure carbon molecules C-n are currently of great experimental and theoretical interest. Our work in this area begins with detection of the SiC molecule, which is isovalent with C-2. New infrared electronic transitions of C-2 and C-3 were discovered by emission spectroscopy of hydrocarbon dicharges. The C-3 and C-5 molecules were found by infrared vibration-rotation spectroscopy of the prototypical obscured carbon star, IRC+10216. C-7 and C-9 were searched for in the same source, but not found. The laboratory infrared emission spectrum of C-60 was recorded to aid in a search for C-60 in extraterrestrial sources.
