Abstract
Terahertz time-domain spectroscopy (THz-TDS) was used to measure the far-infrared absorption spectra of some important biological materials such as Bacillus subtilis spores and dipicolinic acid in the frequency region of 0.2 to 2.0 THz (6.7-67 cm-1). A distinct absorption peak at 1.538 THz was observed in the B. subtilis spores. A dominate absorption mode at 1.54 THz was also observed in DPA powder.
