    Thank so much for very informative lecture. Is there any specific reason to put, memory limit: 200 MW and Shared processors: 8? Also, I want to know how to find ground state energy of any molecule with excellent accuracy using gaussian software? Could you please provide me the details? Thanks once again!

    Thank you so much for this video. Thank you so much for your efforts. Eagerly waiting for the next video. If you also mention that how to create new folder in Dirac, the commands you are using to submit the job, etc, will be more helpful for them who are completely new with gaussian.
    Thanks again.

      The next video is already online. You may also search the commonly used commands online. Dirac is accessed via central facility offered by our institute and hence tricks of the trade can't be discussed in detail on public forum.

    Sir...how much time it needs to optimize a novel complex molecule?

    • @sarasijadas8627
      @sarasijadas8627  7 месяцев назад +1

      Thanks for reaching out to me. It depends on the number of processors and memory limit you assign. Also, it varies from molecule to molecule.

    Sir I run energy first instead of optimising. Does it affect any of the data.

      @sarasijadas8627  7 месяцев назад

      Thanks for reaching out to me. In case of single point energy calculation geometry is unaltered. However, it's recommended to run Opt+Freq calculation first and then single point energy calculation.

      Hi, thanks for reaching out to me. You need Gaussian software to run calculation. GaussView is just a visualization software.
