✦ Synopsis

Intramolecular vibration-vibration energy transfer cross sections have beer. calculated for COz (0001) + H2,!Dz -+ COz(ll'0) + Hz/Dz,+ C02(10°0) + Hz/D*, and-C02(20°0) + Hz/D2 based on the mechanism that the energy mismatch is transferred to the translational motion. For CO2 + Hz. the calculated cross section for C02(OO"1) + Hz -+ CO1(lOoO) + Hi is in good agreement with experimental data. Cross sections for the processes (OOOl + 11 1 0) and (OOOl -20°0) are found to be too small compared with experimental data. For CO2 + D2, (OO"l -10'0) is also the most important process and appears to represent experinicntal data at room temperature. The sum of three cross sections of CO2 + H2 is always greater than that of CO2 + D2 over the temperature range of 100-2500 K.
