Hi all,
I am doing geometry optimization using qchem 6.1 and during optimization, I faced this issue:
        SF-DFT Excitation Energies              
(The first “excited” state might be the ground state)
Excited state   1: excitation energy (eV) =   -1.9774
Total energy for state  1:                 -1798.28494472 au
<S**2>     :  0.0547
S(    2) → S(    1) amplitude =  0.9837 alpha
Excited state   2: excitation energy (eV) =    0.4749
Total energy for state  2:                 -1798.19482563 au
<S**2>     :  2.0123
D(  139) → S(    1) amplitude = -0.6535
S(    2) → V(    1) amplitude =  0.7305 alpha
Excited state   3: excitation energy (eV) =    1.4458
Total energy for state  3:                 -1798.15914456 au
<S**2>     :  0.1320
D(  134) → S(    1) amplitude = -0.1859
D(  139) → S(    1) amplitude =  0.6652
S(    2) → V(    1) amplitude =  0.6249 alpha
S(    2) → V(    7) amplitude = -0.1761 alpha
Excited state   4: excitation energy (eV) =    2.0792
Total energy for state  4:                 -1798.13586893 au
<S**2>     :  1.0574
D(  135) → S(    1) amplitude = -0.6099
D(  137) → S(    1) amplitude = -0.1678
S(    1) → S(    1) amplitude =  0.4894 alpha
S(    2) → V(    2) amplitude =  0.5253 alpha
S(    2) → V(    3) amplitude =  0.1947 alpha
