However, generally not full information in the whole THz range can be obtained due to the limited detection bandwidth (usually less than 5 THz) of the traditional THz-TDS systems. In this paper, effective THz absorption spectra in 0.5\u201310 THz range of five typical nucleobases of DNA\/RNA are characterized with a super broadband THz detection technique, called the air-biased- coherent-detection (THz-ABCD) technique. Few unexpected characteristic absorption peaks appeared in the low-frequency region and meanwhile a series of anticipated characteristic absorption peaks are found in the high-frequency region. The fingerprint spectra of these nucleobases are helpful for further analysis on the vibration and twisting behavior of hydrogen bonds, van der Waals and electrostatic forces etc. between and within DNA\/RNA biomolecules.<\/jats:p>","DOI":"10.3390\/s19051148","type":"journal-article","created":{"date-parts":[[2019,3,8]],"date-time":"2019-03-08T09:58:35Z","timestamp":1552039115000},"page":"1148","source":"Crossref","is-referenced-by-count":9,"title":["Characterization of Nucleobases in Broadband Terahertz Spectra from 0.5 to 10 THz with the Air-Biased-Coherent-Detection Technique"],"prefix":"10.3390","volume":"19","author":[{"given":"Miao","family":"Yu","sequence":"first","affiliation":[{"name":"Key Laboratory of Opto-electronic Measurement and Optical Information Transmission Technology, Ministry of Education, Changchun University of Science and Technology, Changchun 130022, China"},{"name":"Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences, Terahertz Technology Research Center, Chongqing 400714, China"}]},{"given":"Shihan","family":"Yan","sequence":"additional","affiliation":[{"name":"Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences, Center of Applied Physics, Chongqing 400714, China"},{"name":"Chongqing Engineering Research Center of High-Resolution and Three-Dimensional Dynamic Imaging Technology, Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences, Chongqing 400714, China"}]},{"given":"Yong-qiang","family":"Sun","sequence":"additional","affiliation":[{"name":"Key Laboratory of Opto-electronic Measurement and Optical Information Transmission Technology, Ministry of Education, Changchun University of Science and Technology, Changchun 130022, China"}]},{"given":"Wang","family":"Sheng","sequence":"additional","affiliation":[{"name":"Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences, Terahertz Technology Research Center, Chongqing 400714, China"}]},{"given":"Fu","family":"Tang","sequence":"additional","affiliation":[{"name":"Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences, Terahertz Technology Research Center, Chongqing 400714, China"}]},{"given":"Xiao-yu","family":"Peng","sequence":"additional","affiliation":[{"name":"Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences, Terahertz Technology Research Center, Chongqing 400714, China"}]},{"given":"Yuan","family":"Hu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Opto-electronic Measurement and Optical Information Transmission Technology, Ministry of Education, Changchun University of Science and Technology, Changchun 130022, China"}]}],"member":"1968","published-online":{"date-parts":[[2019,3,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"310","DOI":"10.1002\/bip.10106","article-title":"Collective vibrational modes in biological molecules investigated by terahertz time-domain spectroscopy","volume":"67","author":"Walther","year":"2010","journal-title":"Biopolymers"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"102033","DOI":"10.1063\/1.3116140","article-title":"Terahertz electromagnetic interactions with biological matter and their applications","volume":"105","author":"Son","year":"2009","journal-title":"J.
