Hamiltonian diatomic rigid rotor

Here eR is the rotational energy of a rigid rotor and r0 is the equilibrium ground state bond length of the diatomic molecule. The total Hamiltonian is thus... [Pg.33]

The rigid-rotor Hamiltonian for a diatomic molecule with the moment of inertia I = pf o is... [Pg.10]

Simple as they may appear, the classical Hamiltonians developed for rigid rotors in the preceding section are conceptually new. In our discussion of diatomic rotations in Chapter 3, the rotational states JM> were obtained as eigenfunctions of the space-fixed angular momentum operators and P =P 4-Jl + P. The space-fixed angular momentum components J, Jy, p obey the familiar commutation rules... [Pg.170]

We are now in a position to determine the rigid rotor energy levels for tops in order of decreasing symmetry. The Hamiltonian (5.8) for a spherical top is functionally indistinguishable from that of a diatomic rotor,... [Pg.173]

For such a rigid rotor atom-diatom system, we have the hamiltonian... [Pg.309]
