Reactions of laser-ablated palladium and platinum atoms with nitric oxide: Infrared spectra and density functional calculations of MNO+,0,- and M(NO)(2) in solid argon and neon
Laser-ablated palladium and platinum atoms react with NO in excess argon or neon to form Pd(NO)(1.2) and Pt(NO)(1.2) as major products. DFT calculations an found to be effective in reproducing experimental results and in assigning observed bands. Nitrosyl cation and anion species are observed with both metals, and a linear relationship is found between the charge and nitrosyl stretching frequencies in Pd(NO)(+,0,-) and Pt(NO)(+,0,-) that allows estimates of charges on supported Pt and Pd catalysts to be made.
