Abstract
The vibrational spectra and far-infrared (IR) absorption of DAST crystal have been investigated by first-principles calculations. The calculated vibrational frequencies have been overestimated and frequency interval have been divided on two-parts: the low-frequency region where lattice phonon modes are the most important and the high-frequency region with main intramolecular contribution in IR absorption intensity.
