摘要: Abstract The magnitude and sign of the first excited triplet state Davydov splitting tetracene single crystal has been calculated. It is found that charge transfer contribution dominant over exchange integral opposite sign. Assuming a Franck-Condon factor 0.20 for 0-0 transition, one gets E − - + ≈30 cm −1 . also shown (−) should be b polarized (+) polarized.
