IR spectroscopy, or infrared spectroscopy, is an analytical technique used to identify and study chemical substances based on their interaction with infrared radiation. It measures the absorption of ...

This resulted in high-resolution IR spectra, which did not just display the vibrational movements of the H 2 S dimer, but also its rotations and tunneling splittings. Tunneling splitting describes ...

The two units in question are “The Little Garden ... Of course, there’s more to spectroscopy than just optics.
