摘要: High resolution spectra of the A 1Σ+→X 1Σ+ system KRb molecule, obtained after excitation using a titanium-doped sapphire laser, were recorded on Connes-type Fourier transform interferometer. Molecular constants first 88 vibrational levels X 1Σ+ state are determined, and potential energy curve is derived up to an internuclear distance 10.419 A (99.3% well depth). The dissociation limit found as De=4217.3 (15) cm−1 (referred bottom well), in good agreement with theoretical predictions Jenc Brandt [J. Mol. Spectrosc. 154, 226 (1992)] who gave De=4220 (20) value De=4217.4 (8) reported by Kasahara et al. Chem. Phys. 111, 8857 (1999)].
