Iodine Molecular Valence State And Ion State Spectroscopy

The dye laser output has been used to excite iodine molecule and to study the fluorescence excitation spectra of iodine molecule BFI 0: state. The molecular constants of BIT O state such as dissociation limitation, dissociation energy, force constants, vibration fundamental frequency, inharmonic constant of Bill Q state and dissociation energy of X拁I + state have been calculated. The double output of g YAG laser(532nm) has been used as excitation source, utilizing LIF technology, the fluorescence spectra of iodine molecule equal frequency three photons high excited state has been studied, its excitation transition channel and fluorescence emission channel have been discussed. The fluorescence of 479nm, 436nxn, 405nm, 366nm have been attributed on the basis of the experiment, the transition of + 1^棐++ + 3+ FO u ⁴ Lg(Og) for 479nm and 366nm, the transition of FO ^>FIg(Og) for 436nm, the transition of FO ?^Z (O⁾ for 405nm. Two-color, two-resonance fluorescence excitation spectra of iodine molecule , by using YAG laser double output and dye laser output to act on iodine molecule, is observed, identified and analyzed, and attributing the vibration order between 55000cm?and 58000cm?of energy for vibration excitation state ofF?0 state wi^F(1S^<sup>扗.
