Finding Help with Computational Chemistry on PF

AI Thread Summary
The discussion centers on a user's experience with Gaussian software for calculating optimization and UV spectra of organometallic compounds, specifically using the B3LYP/6-311G basis set. The user encounters a syntax error due to incorrectly including the job name in the geometry optimization line. A solution is provided, suggesting the removal of the job name to resolve the error. Additionally, there is a request for advice on the appropriate basis set and functional for calculating molecular orbital energies for compounds containing carbon, hydrogen, nitrogen, and copper.

Hello everyone, I hope you are doing well?

Recently, I’ve been trying to calculate the optimization and Uv spectra of organometallic compounds using the Gaussian software .it’s my first time for the computational chemistry and I am inexperienced . When I run the measure using B3LYP/6-311G basis set I have an error in my calculation and I don't know what the problem is. So, I would be grateful if you show me how to solve it and could you give me the advice about the proper basis set and functional to calculate the MO energies knowing that I have C,H,N and Cu as atoms . And I attach the message received.

Thank you very Much

It looks like for some reason you’ve put the name of your job in the geometry optimization line. Gaussian is trying to read it as an option and is throwing a syntax error as a result. Remove that part and it should probably work.
 
I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
