【摘要】 报道了计算127I2B X跃迁谱线频率及谱线的超精细分裂的频率间隔的经验方法。利用该方法,计算了532nm附近的127I2吸收谱线的频率、波长及相对强度,同时确定了各谱线的振转跃迁。计算结果与实际观测很好地吻合,并预言了532nm附近127I2的激发态跃迁吸收谱线。对已观察到的3条谱线的超精细分裂的频率间隔进行理论计算,简要总结了其分布规律。更多还原

【Abstract】 Reports an empirical method for calculating the frequency of BX transition of iodine molecule and the frequency separations of hyperfine split of the spectra from quantum theory.The frequency,wavelength and relative intensity of spectra near 532 nm were calculated which contain R(56) 320 recommended as the reference spectra for length definition by CCDM(now CCL) and 6 new spectra observed with iodinestabilized Nd:YVO4 laser.Several spectra of excitedstate transition near 532 nm were predicted since they have relative strong intensity from the calculating.The vibrotational band of each transition of spectra was assigned too.The frequency separations of hyperfine split of three observed spectra were calculated.All calculation values match the experimental results very well.更多还原
