BCl_3分子v_3振型吸收峰分别在10.5μ(~11BCl_3)和10.0μ(~(10)BCl_3)附近.利用TEA CO_2激光波长为10.6μ的强红外场,可使~(11)BCl_3分子优先发生红外多光子离解,在残留物中获得~(10_BCl_3的浓缩.Letokhov和Lyman等已发表过在BCl_3蒸汽中分别添加O_2与H_2的实验结果.本文报道利用TEA CO_2激光器的自然振荡谱线,聚焦辐照BCl_3/H_2体系所观察到的硼同位素浓
The absorption peak of v_3 modeled by BCl_3 molecule is around 10.5μ (~ 11BCl_3) and 10.0μ (~ (10) BCl_3), respectively. The ~ (11) BCl_3 molecule can preferentially take place with strong infrared field with TEA CO_2 laser wavelength of 10.6μ Infrared photon dissociation, the residue obtained ~ (10_BCl_3 concentration .Letokhov and Lyman, etc. have been published in the BCl 3 steam were added O_2 and H_2 experimental results reported in this paper TEA CO_2 laser natural oscillation line, the focus of radiation According to the BCl_3 / H_2 system observed boron isotope concentration
