Hi! Dear Sir!
Sir, I want to ask something from you if you could find some free time to answer my query. I would be very thankful to you!
I have optimized some transition metal complexes using B3LYP/6-31G* by Gaussian09. I want to calculate descriptors using Codessa software. So, can I directly use output files from Gaussian (.log files) as input files in Codessa for descriptor calculations? If so, then please share some references. I also need to cite Thank you so much for your time.

Can a Gaussian output file (.log file) be used as an input file in Codessa software for calculating descriptors? Please oblige with a kind response! Also share the reference. Thanks!

For Fe (Singlet, Triplet, Quintet) and Co (Doublet, Quartet), what is the correct energy order between spin states of Fe and between spin states of Co in gaussian (UDFT)?

Could you please make it little more clearer so I can better understand. Because I can see SCF Done= E(UB3LYP) in various places in .log file. I do not know exactly which E(UB3LYP) is the optimized energy.

How I can check manually? I didn't get you. Thank you!

Hi. Dear.
I optimized a transition metal complex at two different spin states as Doublet and Quartet using Gaussian UDFT. Now, I want to calculate the energy difference between the two spin states. For this, I could see two energy values E(UB3LYP) as highlighted in yellow in the attached picture. Which energy value should I consider. Either highlighted on the right side or left side of the image. The attached image is screenshot from .log file at doublet state.
Thank You so much
