Lattice dynamics of polymorphic pyrazinamide drug crystals from inelastic neutron scattering measurements
Lattice-dynamical models of the polymorphic crystal forms of the anti-tuberculosis drug pyrazinamide will help us to obtain a better understanding of the contribution of vibrational entropy and enthalpy to the free energy, and thus relative stability of these crystalline systems. To develop these models it is necessary to obtain accurate information on the low-energy phonon spectra using inelastic neutron scattering measurements. The pyrazinamide system serves as a model system for development of new approaches to structure and properties prediction of molecular crystals.
