The X-ray structural analysis of diglycine hydrogen selenite has been carried out. The substance crystallizes in the monoclinic space group P2 1 /c, a ؍ 12.2651(7), b ؍ 4.8079(6), c ؍ 19.9550(10) A s , ؍ 122.745(4)°, V ؍ 989.73(14) A s 3 , Z ؍ 4, R ؍ 0.0338 for 1647 observed reflection
## Abstract A general model for the vibrational interactions of the hydrogen bonds in molecular crystals is presented. The energy and the intensity distributions of the IR spectra of the 1‐methylthymine and uracil crystals are correctly reproduced.
The vapor grown SbSBr x I 1Àx (x ¼ 0.1; 0.5; 0.9) crystals with clear mirror surfaces have been used for infrared reflection measurements with Fourier spectrometer. The vibration frequencies along c(z)-axis have been derived from Kramers-Kroning and optical parameters fitting analysis of the experim
