How to calculate Gibbs-free energy, enthalpy and entropy change in firefly?

Hello there, I am confused on how to interpret the output file in firefly, I just want to know that, is the TOTAL ENeRGY in :ENERGY COMPONENTS: for the output file is equal to the Enthalpy?...

since I worked on radicals I can't use runtyp=optimize for mp2, therefore i'll only use energy and it does not give me any information on Gibss-energy, Enthalpy and Entropy...


Does the information in the HF calculations giving those reaction energies Gibbs,enthalpy and entropy is used for calculating the change in Gibbs-energy, change in Enthalpy and change in entropy?

Pls help..I'm really confused.
