An electronic transition with an origin near 19203 cm−1 is observed in vapour produced by YAG laser vaporization of a pressed pellet of Li and Be powders and assigned to LiBe diatomic. Vibrational analysis yields a G″=295 cm−1 and G′=188 cm−1. A preliminary rotational analysis gives r0″=2.59 Å and r0′=3.04 Å. The spectroscopy and the electronic structure are discussed and the experimental molecular
在YAG激光压制Li和Be粉末压成的小球的YAG激光产生的蒸汽中观察到起源于19203 cm -1附近的电子跃迁,并归为LiBe双原子。振动分析产生一个ģ “=295厘米-1和ģ '=188厘米-1。初步的旋转分析得出r 0 ″ = 2.59Å和r 0 ′= 3.04Å。讨论了光谱学和电子结构,实验的分子常数与我们最近的技术从头算算值显示出非常好的一致性。
