摘　　要：在双原子分子核运动的波动方程中，计入分子的振转相互作用项，得出的波函数除与振动量子数有关外，还与转动量子数有关．用该波函数编程序计算了ＢＦ分子Ａ１Π→Ｘ１Σ＋带系和ｂ３Σ＋→ａ３Π带系的ＦｒａｎｃｋＣｏｎｄｏｎ因子．计算中转动量子数的取值由Ｊ＝０取至Ｊ＝２００，结果适用于低温、高温和强激波条件．From the nuclear Schrdinger equation of a diatomic molecule with the vibration rotational interaction term,we derive a wave function which is related not only with vibrational quantum number, but also with rotational one.The Franck Condon factors of the two band systems A 1Π→ X 1Σ + and b 3Σ +→ a 3Π of BF are calculated by use of the derived wave function with the rotational quantum number ranging from J=0 to J =200.The results obtained can be used in the cases under low or high temperature condition,and also that under the condition of strong shock wave.
