Direct calculation of dynamic densities
Direct calculation of dynamic densities is a scholarly work, published in 1976 in ''Acta crystallographica. Section A, Crystal physics, diffraction, theoretical and general crystallography''. The main subjects of the publication include quantum, materials science, thermochemistry, physics, chemical education, convolution, molecule, Fourier series, chiral column chromatography, numerical integration, series, computational physics, mathematics, Fourier transform, and statistical physics. It will be shown that, in the convolution approximation, dynamic densities of molecules can be calculated directly from temperature factors and quantum-chemically calculated (static) densities, i.e. without recourse to numerical integration and without calculating Fourier coefficients and series.
