Energy calculated at CID/3-21G
| | hartrees |
| Energy at 0K | -2598.937259 |
| Energy at 298.15K | -2598.940666 |
| HF Energy | -2598.814599 |
| Nuclear repulsion energy | 77.872266 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
