Force constants for U–O bonds in uranyl compounds are readily calculated from the frequencies of the symmetric and asymmetric stretching vibrations determined from Raman and infrared spectroscopy. U–O bond lengths have been calculated from bond force constants using Badger's relation for seven minerals and three related compounds. Where x-ray data exist there is satisfactory agreement between bond lengths determined by the two methods.
Zeitschrift für Kristallographie – Crystalline Materials offers a place for researchers to present results of their crystallographic studies. The journal includes theoretical as well as experimental research. It publishes Original Papers, Letters and Review Articles in manifold areas of crystallography.
