HELIUM NANODROPLET ISOLATION SPECTROSCOPY OF NO$_{2}$ AND VAN DER WAALS COMPLEXES

Abstract

We will report the infrared laser spectra of NO$_{2}$, NO$_{2}$-N$_{2}$, NO$_{2}$ - H$_{2}$O and NO$_{2}$ - O$_{2}$ complexes using Helium Nanodroplet Isolation (HENDI) Spectroscopy. These molecules were excited using an ARGOS cw PPLN OPO (Aculight) in the 3.2 - 3.9 $\mu$m spectral window and we excited the $\nu_{1} + \nu_{3}$ transition of NO$_{2}$.
