Electron diffraction phosgene

The most extensive application which was made of the resonance curve was to the carbon-chlorine bond in phosgene and the chloroethylenes. In the electron-diffraction study of these substances2 the carbon-carbon and carbon-oxygen doublebond values 1.38 and 1.28 A. were assumed the question accordingly arises as to what effect the new double bond values would have on the carbon-... 

The simplicity of the structure of phosgene has precipitated many structural and spectroscopic studies. This Chapter summarizes the results of the studies by electron diffraction, microwave and vibrational spectroscopy, nuclear magnetic resonance and nuclear quadrupole resonance spectroscopy, and mass spectrometry. Studies by electronic absorption and emission spectroscopy, and photoelectron spectroscopy, are discussed in Chapter 17. 

The first structural determination of phosgene was an electron diffraction study performed by Dornte [549], which was rapidly refuted and reevaluated by Pauling and coworkers [277e], and then refined by Bauer [141]. It is ironic to note that, in the light of... 

In an excellent and lucid article (ideal for teaching purposes), phosgene has been used as a case study for the complementary use of electron diffraction and microwave spectroscopy for precise structure determination [1476]. Full details of this study have also appeared elsewhere [1479,1481], and these data provide the most precise structural details yet determined for phosgene.
