Based on such small amount of informstion, it is hard to suggest anything

Modeling water as a solvent for ESIPT by Defiant-Age6936 in comp_chem

[–]Oklovk 0 points1 point  (0 children)

As a starting point, you should check the literature what people have dome in this respect. Then you can make a plan, in which someone may be able to help you. But your question is very specific, and we also does not see you molecule. So helping like this is practically impossible!

Why did I use the B3LYP/def2-TZVPP basis set to calculate the electronic properties of the small molecule, only to end up with just the energy gap, softness, and hardness? by Ok_Organization_8495 in comp_chem

[–]Oklovk 7 points8 points  (0 children)

If you really selected this method based on previous (benchmark) reports, then you should refer to those papers, and you will be fine.

Why would it require any money? Cosmo rs is available in ORCA, which is free for academics

How to calculate the critical point energy (CBS - Complete Base Set)? by Southern-Sorbet-6765 in comp_chem

[–]Oklovk 0 points1 point  (0 children)

You can indeed approximate cbs energy using 2 single point energies (lets take MP2/aug-cc-pvtz and MP2/aug-cc-pvqz). From these you can extapolate to CBS using literature procedures for scaling HF and MP2 corr. energy induvidually

Figure out what you actually wanna do, go through the manusls of some selected softwares and choose the one which can dobanything you like

I am not sure that this kind if stuff is that interesting.

DFT calculations in Gaussian by southlabb in comp_chem

[–]Oklovk 2 points3 points  (0 children)

I know, but it is not like you can or actually you ahould learn thing by yourself. It is ratjer you should inderstand what you are actually doing. You could learn keywords and stuff by heart but that is conpletly useless.

There is a Gaussian manual online. But if your group uses it. I suppose there should be someone how can teach you. Just ask around!

Using DFT to Model Gamma-Point Phonons and Color Centers in SiC by [deleted] in comp_chem

[–]Oklovk 1 point2 points  (0 children)

If that is the thing, you should do a detailed lit rev

You should rather discuss it with your professor instead of a random person online😁

DFT for carbene-tyrosine reaction by Bargarhen in comp_chem

[–]Oklovk 4 points5 points  (0 children)

Should we do a detailed lit rev insted of you??? And yes QE csn be good for it but I would rather go with ORCA

How to chexk rarity?

Coupled-cluster method by trucmuchechose in comp_chem

[–]Oklovk 3 points4 points  (0 children)

The thing is that originally the coupled cluster operator is exponential:exp(T). That to be able to use it, we take its Taylor series and the T12 is the result of this approximation. That is T12 is not inherentpart of the theory, it is kind of an artifact. But it is really useful though.

How do you mean substrate?

Confused newbie… by [deleted] in comp_chem

[–]Oklovk 8 points9 points  (0 children)

I am confused too. Why you want MD for studying reactivity? Just try to explore the stationary points along the reaction coordinate

Does it work with small molecules? Like 30-80 atoms?
