Abstract
A mode-hop free tunable external cavity quantum cascade laser (Daylight Solutions) is used to probe the vibrational dynamics of helium solvated H$_{2}$O and NO$_{2}$ monomers and dimers. The demonstrated high output power and mode-hop free tuning of the laser in combination with a multipass cell and bolometric detection allow for high resolution spectroscopy studies of helium solvated molecules between 10 and 5 $\mu$m.
