Application of Neutron Scattering in Amino Acid Crystals – Structural and Dynamical Information
نویسندگان
چکیده
In this work results of neutron powder diffraction and inelastic neutron scattering on ali‐ phatic amino acid (L-alanine, L-valine and L-leucine) crystals are presented. The study al‐ lows inferring important informations about both the stability of the structures and the dynamics of phase transitions. In particular, it was possible to compare the behavior of different amino acids and to infer that changes in the mean-square displacements ob‐ served for two deuterated forms of L-alanine ND3 – C2H4 – CO2 and NH3 – C2D4 – CO2 are due to a structural rearrangement related to thermally activated amplitude reorientation of NH3 and CO2. Conformation changes in L-valine and L-leucine related to the phase transition are also discussed.

Neutron scattering is proved to be a vital probe in unveiling the magnetic properties of high temperature superconductors (HTSC). Detailed information about the energy and momentum dependence of the magnetic dynamics of HTSC have been obtained directly by this technique. Over the past decade by improving the crystal growth methods, large and high quality single crystals of HTSC, which are ess...
متن کاملVibrations and Diffusion of Atoms in Superionic Crystals and Melts
Recent computer simulation studies contain sufficient information about the atomic disorder and motion to allow a calctlation of the dynamical response of superionic crystals and melts which may be compared with measurements of inelastic neutron scattering and Raman scattering. The high frequency part of this response is essentially that of anharmonic vibrations in a disorderd lattice. The low ...

In this work, experimental and data analysis procedures were developed and applied for studying amino acid crystals by means of X-ray phase measurements. The results clearly demonstrated the sensitivity of invariant triplet phases to electronic charge distribution in d-alanine crystals, providing useful information for molecular dynamics studies of intermolecular forces. The feasibility of usin...
متن کاملStructure-property relations in crystalline L-leucine obtained from calorimetry, X-rays, neutron and Raman scattering.
We have studied the amino acid L-leucine (LEU) using inelastic neutron scattering, X-rays and neutron diffraction, calorimetry and Raman scattering as a function of temperature, focusing on the relationship between the local dynamics of the NH(3), CH(3), CH(2) and CO(2) moieties and the molecular structure of LEU. Calorimetric and diffraction data evidenced two novel phase transitions at about ...
