The n 5 (A 2u ) and n 7 (E u ) C-F stretching fundamentals of hexafluoroethane, C 2 F 6 , have been recorded in a supersonic jet by diode laser absorption spectroscopy. The parallel 5 1 o band is accompanied by five satellite bands, of which three have been assigned to hot bands. A fourth satellite
The infrared spectrum of chromium hexacarbonyl near \(2000 \mathrm{~cm}^{-1}\) has been rotationally resolved by cooling in a supersonic jet.

The laser-induced fluorescence excitation spectrum of jet-cooled 2methylanthracene (2-MA) near the S,-So origin reveals a prominent torsional progression due to the internal rotation of the methyl group or its torsional vibration against the aromatic ring frame. From the torsional level spacings a l
