First-principles study of fluorination of L-Alanine Available to Purchase

First-principles calculations based on Density Functional Theory have been done on effect of fluorination of an important amino acid - L-Alanine. Its structure has been simulated. The unit cell is orthorhombic with lattice parameters a=5.90Å, b=13.85Å and c=5.75Å with volume 470 (Å)³. Bond lengths and bond angles have been estimated. Electronic Density of States calculations show that the material has a band gap of 4.47eV. Electronic band structure indicates that the material can be effectively used for NLO applications. The electronic contribution to the dielectric constant has been calculated and its average value comes out to be 2.165.
