Dear Edgar

The activation energy of any reaction can be calculated using thermochemical calculations in gaussian. However, I do not understand what you mean by vtst. see the following link for the calculation of activation energy:

Dear mudar, I really apreciate your contribution. Vsts, means "variational transition state".
