In the case of CO, the 2s atomic orbital on Oxygen is much lower in energy than the 2s atomic orbital in carbon. The discrepancy in energies allows the 2p-pi and 2p-sigma molecular orbitals to sink lower than the 2s-sigma* orbital in the MO diagram. For this case the calculations ...
AM1 calculations show that the average C-H‚‚‚O bond energy (per dimer unit) is 3.2, 3.6, 3.8, and 3.9 kcal mol-1 for I, II, the tetramer, and (15) Braga, D.; Grepioni, F.; Biradha, K.; Pedireddi, V. R.; Desiraju, G. R. J. Am. Chem. Soc. 1995, ...
Photoelectron spectroscopy provides answers to these questions. In narrow band solids, like the actinides, the interpretation of results requires the use of band calculations in the itinerant picture, as well as models of final state emission in the atomic picture. From the experimental viewpoint: ...
I think this is a very good way to at least probe the space of those orbitals that might interact more strongly than others. I think that at least qualitatively you are safe and I see no problem in doing so if you save a lot of time on the CASSCF and CASPT2 calculations. Of course...
