High-Resolution Infrared Emission Spectrum of Strontium Monofluoride

The high-resolution infrared spectrum of gas-phase SrF was obtained in emission with a Fourier transform spectrometer. Approximately 1400 rotational lines from the 1–0 to the 8–7 bands were measured in theX2Σ+ground state of the major isotopomer,88SrF. The Dunham coefficientsYl,mhave been derived from a combined fit of the infrared transitions with microwave transitions that have been previously reported in the literature.
