The Molecular Structure of Nitrogen Dioxide. A Reinvestigation by Electron Diffraction

An investigation of the structure of the nitrogen dioxide molecule has been made by the electron diffraction method. The interpretation of the photographs, which showed rings extending to values of q of nearly 100(q = 40/λ sinτ/2), leads to the following structural parameter values: N–O = 1.20±0.02A, <O–N–O = 132±3°. These values are discussed briefly and compared with those obtained by other methods.
