摘要：
We present the terahertz (THz) time-domain spectroscopy-based study of ribo- and deoxyribonucleosides constituting RNA and DNA in an aqueous solution. These play pivotal roles in the biological information cascade and functioning of the cell. Terahertz spectroscopy is used to examine the low-frequency collective vibrational modes of the given molecules. THz fingerprint spectra of DNA and RNA molecules isolated from the cells could provide crucial information about the constituents and conformations. In addition, we also ascertained the interesting optical properties such as refractive index, absorption spectra, and extinction coefficients of these molecules in the spectral range of 0.1-2.0 THz.
