Abstract

The high resolution infrared emission spectrum of lithium iodide has been recorded with a Fourier transform spectrometer. A total of 1024 transmissions with Delta nu = 1 for (LiI)-Li-7 (from nu = I --> 0 to nu = 8 --> 7), 387 transitions with Delta nu = 2(nu = 2 --> 0 to nu = 6 --> 4) and 504 transitions with Delta nu = 1 for (LiI)-Li-6 (nu = 1 --> 0 to nu = 5 --> 4) have been assigned. The infrared data have been used to determine improved mass-dependent Dunham Y-lm coefficients for the ground X-1 Sigma(+) electronic state. The mass-independent Dunham U-lm coefficients were obtained along with Born-Oppenheimer breakdown constants. Finally, all of the data were fitted to the eigenvalues of the radial Schrodinger equation containing a modified Morse potential function to determine the parameters of an effective ground state potential.
