英文摘要	terahertz absorption spectrum (0.5-4.0 thz) of l-alanine in the solid phase was measured by terahertz time-domain spectroscopy at room temperature. simulations utilizing gaseous-state and solid-state theory were performed to determine the origins of the observed vibrational features. our calculations showed that the measured features in solid-state materials could be well understood by considering the crystal packing interactions in a solid-state density functional theory calculation. furthermore, intermolecular vibrations of l-alanine are found to be the dominating contributions to these measured spectral features in the range of 0.5-4.0 thz, except that located at 3.11 thz.
