Abstract :
The cocrystal of piracetam and 3-hydroxybenzoic acid under grinding condition has been characterized by terahertz spectroscopical technique. Spectral results show that the vibrational modes of the cocrystal are different from those of the corresponding parent materials. The dynamic process of such pharmaceutical cocrystal formation has also been monitored directly with THz spectra.
