Abstract
A new radial distribution function for use in interpreting the electron diffraction photographs of gas molecules has been obtained. Instead of replacing the inverted Fourier integral by a sum the integration is performed by assuming that the shapes of the maxima and minima are those of cosine functions. The amount of scattering matter r2D(r) is calculated rather than the density D(r). Comparison between radial distribution functions calculated by this method and by other methods is made for a diatomic molecule, a nonlinear triatomic molecule (to test resolving power), a linear triatomic molecule and carbon tetrachloride.
