概要
- 論文の詳細を見る
NO<SUB>2</SUB> adsorbed on silica-gel surfaces shows temperature-dependent ESR spectra, which can be explained by assuming a restricted rotation of the NO<SUB>2</SUB> molecule, where the preferred axis is the O–O direction. It is concluded from this observation that a hydrogen-bond force between the oxygen of NO<SUB>2</SUB> and OH groups on the silica-gel surfaces plays a part in the NO<SUB>2</SUB>-silica-gel interaction. It is also estimated, from the observed hyperfme tensor, that the ONO angle may become slightly smaller when NO<SUB>2</SUB> is adsorbed onto the silica-gel surface from the gas phase.
