Phosphorescence transition rate from excited state no. 1
(Triplet->singlet transition, high-temperature limit)
Transition energy: 8.737 eV
or 141.915 nm
Length gauge:
Partial rates (H_SO): X-polarization 1.45786E+05 Transition moment : 1.434E-02
Length gauge:
Partial rates (H_SO): Y-polarization 0.0000 Transition moment : 0.00
Length gauge:
Partial rates (H_SO): Z-polarization 9494.0 Transition moment : 3.660E-03
Phosphorescence - length gauge:
Oscillator strength (/2PI) (H_SO) 7.461901E-06
Dipole strength [a.u.] (H_SO) 2.190450E-04
Dipole strength E-40 [esu**2 cm**2] 1.415134E+01
Total transition rate (H_SO) 5.175992E+04 s-1
Total phosphorescence lifetime (H_SO) 1.931997E-05 s
```

If we use the result of output file, we will find that: lifetime=1.5/((7.461901E-06)*(2*PI)*(1/(141.915E-7)^2))=6.44345082456349E-06 s, which is the 1/3 of 1.931997E-05 s. What's more, we found that this phenomenon is common. Thus, I wanna know this factor 1/3 is the bug or the feature of Dalton Program?
