Vibrational Analysis of Ultraviolet Bands of Lithium Sodium and Potassium Molecules

抄録

More than one hundred band heads were found in the observation of six ultraviolet band systems of Nag molecule already found. The molecular constants of these band systems, together with one band system of Na₂ molecule and five band systems of K₂ molecule which were newly found by the author, were calculated in their vibrational analysis. It was able to determine the dissociation products, the dissociation energy and the symbol of the upper state of all ultraviolet daub systems of Li₂Na₂ and K₂ molecules, in comparing the corresponding band systems with one another according to the next three facts. i) The intensity distribution and the molecular constants of the corresponding band systems of these three molecules are similar to one another. ii) The dissociation energy D calculated by Birge-Sponer's method is greater than the true value D₀ So there exists the next relation ; v₀₀ +D'-D₀" > excitation energy of dissociation products v₀₀+ D'- D"iii) All the upper states of these band systems are singlet
