Abstract

The low-frequency torsional modes of tryptophan were measured by terahertz time-domain spectroscopy (THz-TDS). It was found that there are two dominated torsional vibrational modes at around 1.435 and 1.842 THz. The origin of the observed torsional vibrations are assigned to the chain and ring of the tryptophan molecule.
