Hi
I am new to computational Chemistry.. I am using gaussian but don't know much about it..
How to analyze any reaction in gaussian, any type of analysis ? mean how to make an input of reactants and products e.g.
2H2 + O2 ---> 2H2O how i analyze this, i tried it but it gives an error..
sorry for my bad english..

As I said on the other thread, you are much better off finding online tutorials on getting started in Gaussian.
It is not a trivial exercise and the idea of performing "any type of analysis" is not a good place to start from.
