利用线偶极子近似对通过点偶极子近似得到的Forster能量传递率k进行了解析修正。结果表明，对于共轭长度L远大于分子间间隔R的分子，线偶极子近似预测k类似于(RL)(-2)，类似于(RN)(-2)(其中N是共轭单体单元的数目)。这与点偶极近似相反，点偶极近似预测k类似于(LR-6)-R-2，类似于(NR-6)-R-2。
The line dipole approximation is used to investigate analytical corrections to the Forster energy transfer rate, k, derived via the point dipole approximation. It is shown that that for molecules whose conjugation length, L, is much larger than the separation, R, between molecules the line dipole approximation predicts k similar to (RL)(-2) similar to (RN)(-2) (where N is the number of conjugated monomer units). This is in contrast to the point dipole approximation, which predicts k similar to (LR-6)-R-2 similar to (NR-6)-R-2.
