關于激發(fā)態(tài)的單重態(tài)和三重態(tài)
|
|
由于相干的空穴和電子自旋進動,萌芽復合趨向于形成單重態(tài)激子對。然而,由于電子和空穴隨機捕獲,非萌芽復合產生的單重態(tài)和三重態(tài)激子對的比例為1:3。 原文“The germinate recombination tends to form singlet radical pairs due to coherent electron and hole spin precessions. However, the nongerminate recombination yields both singlet and triplet radical pairs with statistic ratios of 1:3 due to randomspin capture. ” 后面的1:3是怎么來的,沒看懂,求解釋 |

謝謝,麻煩再看下。不可能把整篇文章貼上了,這部分原文the radical-pair formation undergoes spincoherent and spin-random captures, namely germinate and nongerminate recombination, respectively, under photoexcitation. The germinate recombination tends to form singlet radical pairs due to coherent electron and hole spin precessions. However, the nongerminate recombination yields both singlet and triplet radical pairs with statistic ratios of 1:3 due to randomspin capture. The singlet and triplet radical pairs can be mutually converted in both germinate and nongerminate recombination when the spin-flip mechanism is present due to hyperfine coupling (HFC) or spin–orbital coupling (SOC). |
