Thank you very much for your timely suggestion. I attempted to invoke the geometry optimization through Gabedit following the given suggestion but it seems that Firefly does not recognizes the input format with the basis set for specific atoms being recognized as part of the molecule thereby causing some errors in the output file. I believe that I might have missing something in the input file but I just could not figure out the mistake. Would you mind to help checking my output file (as attached) please? I am sorry for bothering and thank you very much in advance.

Best, Tanggo
