Lie Algebraic Approach to Energy Transfer for Collinear Collision of Two Anharmonic Diatomic Molecules

An anharrnonic oscillator algebra model is used to study the collinear collisions of two diatomic molecules.The transition probability for vibration-vibration energy transfer is presented. For an application of the method, we talkabout the collision of N;+CO,N;+O;, and N;+N;. Through long time averaging, the transition probability changesto the function of total energy of the system. Comparing the results with the quantum results, we can see that thedynamical Lie algebraic method is useful for describing the anharmonic diatomic molecular collision.
