Energy calculated at MP2=FULL/STO-3G
| | hartrees |
| Energy at 0K | -1795.910004 |
| Energy at 298.15K | -1795.911094 |
| Nuclear repulsion energy | 74.173467 |
The energy at 298.15K was derived from the energy at 0K
and an integrated heat capacity that used the calculated vibrational frequencies.
