Dear all,
My structure of TDDFT calculation is a linear chain of Na 40. The structure was optimized by VASP. Therefore, VASP structure output file CONTCAR was converted to coor and the structure relaxation was not performed by Turbomole. The dscf calculation is converged, since there is a energy file in my calculation directory. The escf calculation for a2u 200 and a2u 300 are calculated separately. The difference of control file between them is only the excited state number of a2u. However, they have different excited state energy after the 41th singlet excitation.
For a2u 200 calculation
40 singlet a2u excitation
Excitation energy / eV: 0.9921363352821709
41 singlet a2u excitation
Excitation energy / eV: 1.003326534071252
For a2u 300 calculation
40 singlet a2u excitation
Excitation energy / eV: 0.9921363510817086
41 singlet a2u excitation
Excitation energy / eV: 4.922113748874488
Both of above dscf calculation are calculated separately.
The control file for a2u 200 calculation is as follows,

I do not know why the calculation results are not consistent.
Thanks,
