The statistical computation of an ideal gas state thermodynamic functions namely enthalpy, entropy, free energy, heat capacity of 1,2,3 – Trimethoxy benzene, m-methyl methoxybenzene have been performed. These calculations have been made at a pressure of 1 atmosphere in the temperature range 100°K to 1500°K under rigid rotor harmonic oscillator approximation for 1 mole of perfect gas & on the basis of vibrational frequencies obtained from FTIR & Raman spectra & also with the help of moment of inertia.
