| 摘 要： | 基于微分的思想,结合经典的双原子分子跃迁谱线表达式,提出了预言双原子分子P线系高激发振-转跃迁谱线的新解析物理公式.对于某分子电子体系的某一P支跃迁带,利用实验上获得的一组(15条)精确的跃迁谱线和该跃迁带对应的上下振动态的转动常数(Bυ',Bυ″)的精确数据,该公式不仅可以精确地重复已知的实验跃迁谱线,而且还能预测出实验上难以获得的更高激发态的跃迁谱线数据.利用该公式,研究了CO分子电子基态的(2,0)振-转跃迁带的<

| Abstract: | An analytical formula is derived from elementary expression of molecular total energy for calculating the accurate P-branch spectral lines of rovibrational transitions for diatomic molecules. Using the constants (Bυ',Bυ″) and a group of fifteen known P-branch experimental transition lines for a transition band, the formula not only reproduces the known experimental transition lines, but also generates the spectral lines that may not be available experimentally. The P-branch emission spectra of the (2,0) band of the CO molecule are studied in this work, and correct values of the unknown spectral lines up to J = 80 for this band are predicted by using the formula. |
