The rigid-rotor, harmonic oscillator model exhibits a combined rotational-vibrational energy level satisfying EvJ = (v + 1 2 )hν0 + BJ(J + 1). The rotational spectra of non-polar molecules cannot be observed by those methods, but can be observed. This polarisation has. . (2 "0) = 28 "m. As seen, increased strength of hydrogen bonding typically shifts the.

Kisiel, "The high frequency rotational spectrum of 1,1,1-trichloroethane and the observation of K=3 splitting", J. Rotational transitions on the other hand require weak photons in the far IR (20 &181;m and longer). Rotational transition frequencies were referenced to an external clock for accurate absolute frequency measurements. If rota-tional transitions of the molecules are resonant to one or microwave frequency water rotational transitions more frequencies in the chirp, the respective molecules will orient and form a macroscopic dipole moment.
Rotational spectroscopy is concerned with the measurement of the energies of transitions between quantized rotational states of molecules in the gas phase.
