Photoelectron spectroscopy of HCI and DCI using molecular beams, To describe the rotation of an object, the classical mechanics form would describe the energy as, where I is the moment of inertia, ω is the angular velocity, and it is then put into terms of L, the angular momentum, μ, the reduced mass, and r, the bond length.

Sanderson, R.B., Phys., 1975, 11, 217. Because the rotational energy levels are much more closely spaced than the vibrational energy levels, ~20 cm^-1 vs. ~2900 cm^-1, respectively, simple dispersive IR spectroscopy is simply not viable.1 Thus, a higher resolving power is required.
