MOPAC excited state energies



 Dear CCLer's
 I have started using MOPAC to calculate some excited state properties.
 The molecules are a bit too large to handle with CIS methods in Gaussian.
 Anyway, I am not sure how to interpret the output I get from the excited
 state output.  It is:
 STATE ENERGIES  EXPECTATION VALUE OF S**2  S FROM S**2=S(S+1)
     1   -3.771809   SINGLET         0.00000   0.00000
     2   -3.170890   TRIPLET         2.00000   1.00000
     3   -2.796270   SINGLET         0.00000   0.00000
     4    0.100754   SINGLET         0.00000   0.00000
 How do I take this info and calculate the frequency of the transition from
 the ground state to the excited state?
 Any help would be much appreciated.
