Determine the translational, rotational and vibrational contributions towards the molar entropy and the molar specific heat of carbon dioxide at N.T.P. Assume the ideal-gas formulae and use the following data: molecular weight M=44.01; moment of inertia I of a CO2 molecule =71.67×10−40 g cm2; wave numbers of the various modes of vibration: vˉ1=vˉ2=667.3 cm−1, vˉ3=1383.3 cm−1 and vˉ4=2439.3 cm−1.
