Energy calculated at MP4=FULL/cc-pVTZ
| | hartrees |
| Energy at 0K | -114.278631 |
| Energy at 298.15K | -114.280048 |
| HF Energy | -113.835182 |
| Nuclear repulsion energy | 30.697918 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
