FTIR And Raman Studies On Solid Nitrogen Dioxide: Temperature Cycling Of Ordered, Disordered And Multicomponent Layers.

FTIR spectra of nitrogen dioxide layers deposited at various rates and substrate temperatures, are reported. Bands assignable to N2O4(D2h) (ordered and disordered layers), to 0=N-O-NO2 "D" and "D'" isomers, to NO+NO3- nitrosonium nitrate and to the NO2 monomer were observed. The relative amounts of species depends upon deposition conditions. Temperature cycling effects were followed up to 205 K.
