The NIRLAS acronym stands for Near-Infrared Laser Absorption Spectroscopy

In our research we study the overtone spectra of small and medium sized molecules in the gas phase to explore the dynamics of highly vibrationally excited species. We are particulary interrested in possible photochemical processes initiated via overtone excitation and in possible atmospherical implications of such processes.

We use near infrared tuneable diode lasers and supersonic jet expansions to measure spectra with simplified rotational structure at very high spectral resolution.

We target small to medium size polyatomic molecules, such as methane (CH4), ammonia (NH3) or methanol (CH3OH) to track, how the complexity of overtone vibrational spectra changes with size of the absorbing species.
