Lay Summary (English)

Lay summary
This project seeks to apply multiple-laser techniques to extract information from small molecules important in the atmosphere (i.e., water) as well as biological molecules produced in the gas phase by electrospray.

In the first part, we measure energy levels of the water molecule at energy near and above its dissociation threshold, the purpose of which is to understand the absorption of water in the near-UV region of the solar spectrum.

In the second part, we are developing new laser-based techniques to probe gas-phase biological molecules with the goal of providing structural information.
