通常给出的荧光寿命与吸收强度之间的关系式，严格地说，只适用于跃迁为锐线的原子系统。这个P3给出了修正的公式l/ro= 2.880 × 10 ~（-9）n ′（vr）A_（1-l）（！（I/g，，）fEd lnv，当强烈允许跃迁时，这对于宽分子带应该是有效的。由此计算的寿命为; nula已完成3。RD与测量：对于溶液中的许多有机分子，LIFET 1 ~ E5。在大多数情况下，这些值在实验误差范围内一致，表明该公式对此类系统有效。的限制。nula an：l the r~ s：.并讨论了弱跃迁或禁戒跃迁的预期结果。
The equations usually given relating fluorescence lifelime to absorption intensity are strictly applicable only to atomic systems, whose transitions are sharp lines. This p3. per gives the derivation of a modified formula l/ro= 2.880 X 10-9 n'(vr) A,-l (!(I/g,,) fEd lnv, which should be valid for broad molecular bands when the transition is strongly allowed. Lifetimes calculated by this for; nula have been comp3. rd with measure: llifeti~ e5 for a number of organic molecules in solution. In most cases the values agree within experi nental error, indicating that the formula is valid for such systems. The limitation3 of the for. nula an: l the r~ s:. llts expecteJ for weak or forbidden transitions are also discussed.
