Abstract
The high resolution gas phase spectra of InF and DF were recorded with the Bruker IFS 120Hr Fourier transform spectrometer at the University of Waterloo. The spectrum of InF was recorded in the region of $400-600 cm^{-1}$ with a helium cooled Si:B detector at a resolution of $0.006 cm^{-1}$ The DF spectra were recorded in the region of $2200-3300 cm^{-1}$ at a resolution of $0.01 cm^{-1}$. An InSb detector was used and a total of 20 scans were co-added to obtain the spectrum Ro-vibrational data up to $\nu$=12 were obtained for InF and up to $\nu$=3 for DF. Sets of Dunham coefficients $Y_{ij}$ and mass-reduced Dunham constants $U_{ij}$ are determined. The Spectra show evidence of Born-Oppenheimer breakdown.
