VUV Photolysis of silane with nitric oxide in solid neon

We report the results of vacuum-ultraviolet (VUV) photolysis of SiH4 and NO in solid neon at 3 K. Photolysis at 130 nm produced a complex range of products, including SiH2, Si2H6, and various silicon oxides. Additionally, with the support of quantum chemical calculations and D-isotopic substituted experiments, we tentatively identified a new species, H2SiN(H)O, as an intermediate in the reaction of SiH3 with NO. These findings provide new insights into the VUV photochemistry of SiH4 and NO in a solid matrix and offer valuable information for understanding silicon-based combustion chemistry and astrochemistry.
