Temperature effects on heat capacity in four and three component systems N2O-HCN and CO-C2H2, respectively, were computed. Structural and vibrational parameters originated from the second order Møller-Plesset perturbation treatment with the 6-31++G** basis set while relative energies were of a still advanced nature. Isomerism contribution to heat capacity exhibits two temperature maxima at 43 and 205 or 15 and 83 K in N2O-HCN or CO-C2H2. The highest reported isomeric enhancement of the total heat capacity is about 27 %.
