Thank you sir !!!!

I just updated sobEDA tutorial package (//www.umsyar.com/soft/sobEDA_tutorial.zip), Section 6 is added to sobEDA_tutorial.pdf, which discussed how to solve SCF non-convergence problem.

Sir I have tried 4-5 methods by changing the input for sobEDA analysis but in some cases convergence criterion was not met, in some cases total interaction energy was zero. Please can you correct me as I'm new to computational chemistry I didn't get it.

So sir for Tl what should correction i need to do

sobEDA is not compatible with scf=qc. Also, scf=qc is rarely useful. There are many possible ways to solve SCF unconvergence problem in Gaussian, see my blog article //www.umsyar.com/61 (written in Chinese, please use Google translator)
Note that there are many EDA methods, when sobEDA is used, please clearly mention its name.

3 days ago I posted about the problem with EDA analysis for Ga, In, and Tl metals [Tl{Mn(CO)4}5]2-. Now I am facing a problem in the EDA calculation of Tl metal. First I used def2tzvp functional for Tl also but in that case, an error occurred which said that the convergence criterion was not met then I added scf=qc but now the calculation is running for 3 days and has not been completed generally EDA calculation doesn't take more than 8 hrs.
Please can you tell me what error am i facing? I have sent an email of the input file which I made.
