The vibrational relaxation equation for polyatomic gases is formulated in consideration of the translation-vibration and the vibration-vibration energy transfers. The multi-quanta transitions of vibrational states and the simultaneous couplings among any numbers of vibrational modes are allowed in the vibrational energy transfers. On the basis of this relaxation equation, the energy relaxation of each vibrational mode in CO_2 is analyzed. The effect of the V-V couplings between mode ν_3 and modes ν_1+ν_2 on the relaxation of mode ν_1(ν_2) is not appreciable due to the small vibrational heat capacity of mode ν_3, and the apparent relaxation rate for mode ν_1(ν_2) is nearly equal to a mean rate constant K_∞ of the T-V processes of modes ν_1 and ν_2. If the rate of the intramolecular V-V couplings of mode ν_3 with modes ν_1+ν_2 is comparable to or larger than K_∞, the apparent relaxation rate of mode ν_3 is also very close to K_∞. This is the reason why a multiple relaxation has not been found experimentally in CO_2.
