Energy calculated at G3
| | hartrees |
| Energy at 0K | -114.347807 |
| Energy at 298.15K | -114.343960 |
| HF Energy | -113.783516 |
| Nuclear repulsion energy | 31.047636 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
