## Abstract Lithium tetraborate, Li~2~B~4~O~7~ (LTB) crystals were grown by Czochralski technique. It belongs to tetragonal system with lattice parameter a = b = 9.479 ร , c = 10.286 ร . Transmission range of this crystal is 170 nm โ 3300 nm. This material has attracted much attention because of its
Calculated ro-vibrational energy levels (J ~< 4) and transition intensities are presented for the two most abundant isotopomers of Li~. The calculations use the recent ab initio potential energy surface of ~EARLES et al. (Spectrochim. Acta 43A, 699 (1987); 44A~ 505 (198~;); 44A, 985 (1988))โข The rot
