Recently, attempts to use deoxyribonucleic acid (DNA) as an industrially important substance have been emerging. For that purpose, easy and convenient determination of the high-order structure of DNA is desirable. In this research, we measured far-infrared absorption spectra of various synthetic single-stranded DNAs, each with an identical base in its nucleotides, and found that DNAs with different bases exhibit different spectra. We also demonstrated that the number of thymine bases on a single-stranded DNA can be estimated from the spectra.
