Rotational Spectrum of CBr by Kinetic Microwave Spectroscopy of 193-nm Photolysis Products of Bromoform

We have measured the first millimeter-wave spectrum of CBr. The radical was produced by pulsed UV–laser photolysis of bromoform at 193 nm and detected using kinetic spectroscopy. We have significantly improved the rotational and fine structure constants for the ground vibrational state. The hyperfin...

Zusammenfassung:We have measured the first millimeter-wave spectrum of CBr. The radical was produced by pulsed UV–laser photolysis of bromoform at 193 nm and detected using kinetic spectroscopy. We have significantly improved the rotational and fine structure constants for the ground vibrational state. The hyperfine structure due to the bromine nucleus has been resolved and quadrupole and magnetic hyperfine parameters evaluated for the first time.
