Let's regard the mighty methane molecule (CH4) as a rigid tetrahedron, with the C atom at...
Using the rigid rotor model, calculate the energies in Joules of the first three rotational levels of HBr, using for its moment of inertia I-R2, with u mHm(mH mx) and equilibrium internuclear distance 1.63 Å. To put these energies into units that make sense to us, convert energy to kJ/mol. (Simply estimate atomic masses from the average atomic weights of the elements given in the periodic table). kJ/mol kJ/mol kJ/mol Think about how these sized energies compare with the typical...
