The Rovibrational Spectrum of a Diatomic Molecule (HCl)
This laboratory video explains an experiment to generate HCl in the gas phase and then to acquire its infrared spectrum with an FTIR spectrometer. The data resolves transitions between the individual rovibrational quantum states of the molecule.
