| Popis: | Analysis of the intensities of an interacting polyad of bands is complicated by basis function mixing. Fortunately it is usually possible to find lines belonging principally to one band or to subsets of the polyad to begin an iterative procedure to derive intensity parameters. Five bands of ethylene in the 3 μm region have been investigated for line intensities by this method, using 148 selected measurements of about 6800 Doppler-limited transitions recorded with a difference-frequency laser spectrometer. Finally two band strengths and two Herman–Wallis parameters have been determined with statistical significance, permitting the observed intensities of the pentad to be calculated with 1%. |
