Deuteration allows the identification of several species of vibrations, through the comparison of vibrational spectra of the deutered and hydrogeneted samples. In this work we base studied the vibrational properties of L-valine-d8 (99,8 % atom % D) through the Raman spectroscopy technique. At first, the assignment of all Raman active vibratonal mades of L-valine was revisited, and a comparison with a previous work was done. In particular, several bands associated to stretching of NH_3^+ and stretching of CH3, among others, which are observed in the interval 2000 – 2400 cm-1 were assigned. In the second part of the work, again using Raman spectroscopy, it was studied the vibrational modes of the crystal in the temperature range 100 – 300 K. ...
