Propriedades vibracionais e estruturais do aminoácido DL-Norvalina

Abstract

Amino acids are important for the functioning of the organism of living beings, so the study of these compounds is of fundamental help in the understanding of this functioning. Amino acids are chemical compounds consisting of an amine group, a carboxyl group, a hydrogen molecule and a central carbon-linked radical. The radical linked to the central carbon is what differentiates the various types of amino acids. In this study the vibrational and structural properties of the DL-Norvaline Crystal (C5H11NO2) were studied. The technique for the growth of the crystal was by steam diffusion, taking on average one month for the formation of the crystal. Measurements of X-ray diffraction were performed, confirming the crystalline structure of the sample, and measurements of Raman spectroscopy at ambient temperature in the spectral region between 50 cm-1 and 3200 cm-1. An attempt is made to classify normal vibration modes through comparison with previous works
