Studying the behavior of amino acids when exposed to extreme temperature conditions is the main objetive of this thesis. In the L-valine (C5H11NO2) infrared absorption measurements were performed, while Raman scattering measurements were performed in α and β forms of L-glutamic acid (C2H9NO4). On the L-valine, the infrared apparatus allowed two types of measurements: the former the interval was ~10 to ~700 cm ̄ ¹ (comprising the far-infrared region); the latter the range was 370 – 4000 cm ̄ ¹ (encompassing the region known as mid-infrared, the thermodynamic parameter temperature assumed values between 100 K and 300 K spaced apart by 20 K. In the Raman measurements one has been got a spacing of 50 K with a temperature ranging from 18 to 300 ...
