Abstract
Ab initio RHF SCF/3-21G calculations have been carried out to determin e the equilibrium geometries, vibrational frequencies and intensities of the intermolecular modes of uracil and 1-methyluracil dimers. The r esults are compared with the experimental low frequency infrared and R aman spectra of the crystals. The dimer approximation for hydrogen-bon ded crystals is discussed.
