A hydrogen molecule in it's ground vibrational state with KE=10eV coollides with heavy atom metal surface and no energy is transferred to the surface. The surface can be modeled as an infinite potential wall.The molecule/surface collision can be modeled as freely moving molecule in 1D both before an dafter the collision. The collision is otherwise inelastic so some of the transifional energy is transferred ot into higher vibrational states of the molecule.1. Why can the rotational states of the molecule not be cosidered in this model?2. Before the collision what is the complete Eigen-function of the molecule? assuming the surface is located at x=0, and V (x<=0)=infinite and V(x>=0)=0 and tha tthe molecule is located at a position X>>0. which means the molecule can be treated as a free mass in the region 0<x<infinite.3. What's the total Energy Eigen-value for the molecule in this incoming state?
