- Dear All,
- Are there any rough guides (in written form or otherwise) as to
- which invocation of HF SCF methods above is suitable for a particular
- problem. I'm sure (well not that sure !) that given enough time I could
- understand all the maths and physics required to make wise choices
- myself. I would imagine there is more to it than simply
- considering 'open shell'
- or 'closed shell' systems. Can anyone throw any light on this please ?
- My partucular interest is transition metal complexes.
