摘要: NO rotational analysis of an electronic transition has been reported for a molecule containing as many ten atoms. However, preliminary spectrograms pyrazine (Fig. 1) showed fine structure clearly susceptible to 2). Twelve bands which were relatively free from overlapping photographed in the fourth order 150,000-line grating, and constants accurate band centres obtained. Similar treatment was possible 3200 A. absorption pyrimidine 3700 by pyridazine. The obtained respective 0–0 are :
