I'm doing the theoretical emission of excited state T1 of Pt complex. The .out file presented a phosphorescence transition. How to change the keywords if I want to get more transitions. The following is .dal file
**DALTON INPUT
.DIRECT
.PARALLEL
.RUN RESPONSE
**INTEGRALS
.SPINORBIT
**WAVE FUNCTIONS
.DFT
B3LYP
*SCF INPUT
**RESPONS
*QUADRATIC
.ECPHOS
.PHOSPHORESCENCE
.PRINT
10
.ROOTS
1
**END OF INPUT
In addition, Why there are three Oscillator strengths behind the transitionenergy in .out file? What do these oscillator strengths represent?

Re: How to calculate phosphorescence
Increase .ROOTS to the number of excited states you want to calculate. The three components printed correspond to the three components of the electric dipole operator. Normally, you would be interested in the isotropic average of these components, and this is also printed in the output.
