If a H2 molecule rotates in the plane of a crystalline surface (in a chemisorption situation), it can be approximated as a two-dimensional rigid rotor. Calculate (in kJ/mol) the lowest energy rotational transition (transition from the J=0 to J=1) for such a system. Take the reduced mass of the rotor to be 8.3678 x 10-28 kg and the value of ‘r’ to be 0.7416 Å.
