Laser-Stark spectroscopy of fluoromethane in a molecular beam

The laser-Stark spectrum of the ν₃ vibration of fluoromethane in a molecular beam is recorded using bolometric detection methods. The resolution of the spectra is limited by the homogeneity of the applied electric field to one part in 3000 of the Stark shift required to tune a transition into resonance. The observation of several field induced transitions of fluoromethane is reported.
