Abstract

The high-resolution infrared emission spectrum of boron monofluoride was recorded with a Fourier transform spectrometer. There are 359 transitions of (BF)-B-11 with v = 1 --> 0 to v = 5 --> 4, and 94 transitions of (BF)-B-10 with v = 1 --> 0 to v = 3 --> 2 assigned. Improved Dunham Y-ij coefficients for the ground X(1) Sigma(+) electronic state were determined from the infrared data combined with existing microwave data. The mass-reduced Dunham U-ij coefficients were also obtained along with Born-Oppenheimer breakdown constants. An effective Born-Oppenheimer potential was determined by fitting the available data to the eigenvalues of the radial Schrodinger equation containing a parameterized potential function. Finally, the relative transition dipole moments of the major isotopomer (BF)-B-11 were also measured. For AlF, our previous measurements were extended to higher v add J, in order to obtain improved Dunham coefficients and an improved internuclear potential. (C) 1995 Academic Press. Inc.
