| 摘 要： | 用Fortran90自编程序计算了甲醛(H2CO)分子的总的配分函数,同时也计算了H2CO分子000010-000000和100000-000000跃迁带在296～3000 K下的线强度.将计算结果与HITRAN数据库提供的结果进行了比较,得出:在296～3000 K两者数据符合很好,这表明高温下分子配分函数和线强度的计算是可靠的,由于3000 K以上H2CO分子的相关光谱数据不容易从实验获得,在理论上模拟了H2CO在高温条件(4000 K)下的线强度和模拟光谱.

| Abstract: | The total internal partition sums of formaldehyde were calculated by Fortran90 program.At the same time the line intensities of 000010-000000 and 100000-000000 transition bands of formaldehyde at several temperatures ranging from 296 to 3000 K were computed.Results showed that at this temperature range the agreement between the calculated line intensities and those extrapolated from HITRAN database is fairly good,which provides a strong support for the calculations of partition function and line intensity a... |
