The infrared spectra of OH radical isolated in solid neon have been investigated by Fourier Transform infrared spectroscopy (FTIR). OH monomer was prepared by microwave discharge of a mixture of water and neon gas at different concentrations prior to deposition on the cold mirror at 5 K. The microwave discharge of H$_2$O/Ne system is remarkable due to its propensity to form OH radical and other species like H$_2$, HO$_2$, OH-HO$_2$, OH-H$_2$O and (OH)$_n$-H$_2$O and IR spectroscopy reveals a variety of phenomena far from being fully understood. OH concentration studies, D/H isotopic substitution, and subsequent annealing leads to the characterization of the different species trapped in the neon matrix. All vibrationnal mode of OH-H$_2$O complex have been detected. The presence of species such as H$_2$ and HO$_2$ after matrix deposition led us to carry subsequent UV photolysis of our samples where the complex OH-H$_2$O may also be formed by following reaction: HO$_2$-H$_2$ + h$\nu$ $\rightarrow$ OH-H$_2$O en_US dc.language.iso en en_US dc.publisher Ohio State University en_US dc.title THE VIBRATIONAL STRUCTURE OF OH RADICAL AND OH-H$_2$O COMPLEX: A MATRIX ISOLATION STUDY en_US dc.type Article en_US
