Analyse des spectres de vibration de la β-alanine, de la taurine et de la ciliatine-β

Infrared and Raman spectra of solid β-alanine, taurine and ciliatine (β form) are analysed. A normal mode calculation is made. The given valence force fields of the three crystalline molecules are very similar. It shows the N—CαH2—CβH2— radical is electronically equivalent in the three molecules.
