Energy calculated at TPSSh/6-31G(2df,p)
| | hartrees |
| Energy at 0K | -114.424610 |
| Energy at 298.15K | -114.426023 |
| HF Energy | -114.424610 |
| Nuclear repulsion energy | 30.565479 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
