Exercise 4: Exploring the Effect of Theory and Basis Sets
Using WebMO/Gaussian please complete the following table by optimizing the geometry based the stated level of theory and basis set:
| Basis Set | C-H bond length |
| Minimum: STO-3G | |
| Basic: 3-21G | |
| Routine: 6-31G(d) | |
| Accurate: 6-311+G(2d,p) |
| Theory | C-H bond length |
| HF | |
| Moller-Plesset 2 | |
| B3LYP |
See the reported experimental C-H bond length here.
Please email the completed tables Friday 10 am...if you need more time, just ask.
