    I have been watching so many videos for almost a year, this gave me a clear idea about calculation. Thank you very much :)

    Thank you so, so much! It may be hard for beginners to extract useful data from Gaussian's output, but you make it so simple. If you could make more videos like this, showing how to get another properties, that would be great. Good job!

    What's the meaning of such huge values like, e.g., -242114.896 kcal/mol for naphthalene by B3LYP/6-311++G(d,p)? Is it related to an exothermic process?

    Interesting. I wonder whether it is possible to model the thermal decomposition of a metal alkoxide to give the related oxide.

    Dear Prof., hi. You are working nicely and enthusiastically. Make a video explaining how to choose the appropriate hybrid functional & basis set for specific transition metals for inorganic clusters like [XM12O40]n-, Polyoxometalates (POMs) are clusters of units of oxoanions of transition metals, such as Mo, W, V and Nb.

    Although not always deal with these two compounds (Naf and Azu), it was possible to realize that the average of the absolute and relative errors are +/- 7.68 and 22% for AM1 model. In this article, five different models were used (small number compared to all possible models that exist or will exist). In the face of numerous options to calculate theoretically the heat of formation and the impossibility of performing experimentally considers appropriate to use basic tools of statistics to assess the five processes when obtaining results should not be too need? (after all for various compounds is impossible to predict when a researcher will have interest to evaluate the compound that interests us today) Based on what I see error always will occur from computational methods, but its usefulness is huge when the experimental procedures are not feasible or delayed, I believe that for chemistry intusiastas the statistical observation of a set of data would be a route to certain decision-making as it would reduce the number of trial and error to achieve a practical result. For example, instead of obtaining all computational data for the reaction may use an existing and already fraction table and other computationally obtained.

    Possible, but definitely not easy. I know several group that have tried to model alkoxide rxn in water to form the related oxide and this is much harder than my simple example. Primarily because it forms a solid oxide (e.g., TEOS and water to form SiO2) and this is hard to model. Gaussian does have periodic boundary conditions but often this rxn form glasses not crystals.

    Unfortunately, Gaussian 09 and GaussView 5 is NOT freeware. We have a site license at ASU for mac, pc and linux. However, in general this is not freeware and cannot be used without purchasing the software AND it is expensive. freechemical.info is a website provides some freeware options.
    I like NWchem, Gamess and a few other ab initio software packages. However, I have never found any good GUI for front-end molecule building.
