Maesurement of the vibrational band strength of 11BF using a tunable diode laser

Article abstract of DOI:10.1063/1.441854

The infrared band strength for the fundamental vibrational mode of 11BF is measured by line absorption of the P(11) transition at 1343.5 cm^-1 using a tunable diode laser and multipass absorption cell coupled to a discharge flow apparatus.TheBF number density is simultaneously determined by ultraviolet absorption at the bandhead of the A ¹Π<-X ¹Σ transition at 196 nm.The resulting value for the band strength is 650 +/- 200 cm^-2 (STP atm)^-1, which is in good agreement with existing theoretical calculations.
