Popis: The high-resolution vibration-rotation spectrum of InF was observed by a diode laser spectrometer. The Δ v = 1 transitions of 115 InF and 113 InF were observed for v ′ = 1 to 9 and for v ′ = 1 to 4, respectively, in the wavenumber range 456-564 cm −1 . They were analyzed in a least squares fit to a set of twelve Dunham Y ij coefficients for 115 InF, where usual isotopic mass relation was used for the fit of the transitions of 113 InF. It was found that the usual isotopic mass relation did hold within the present experimental errors. The Y 10 , Y 20 , Y 30 , and Y 40 were determined to be 535.36304(24), −2.67244(11), 8.446(19) × 10 −3 , and −1.52(11) × 10 −5 cm −1 , respectively, with the standard errors in parentheses. The Dunham potential constants for InF were also determined.
