摘要

Terahertz region in the vibrational spectra of a certain molecule reveals the intramolecular vibrations between weakly bonded or non-bonded groups. Additional information can be acquired by photo-induced transitions between metastable states of the target agent. Different isomers of stilbene and its derivatives can be utilized in order to obtain the spectral terahertz fingerprint using multi-state spectral sensing technology. Also stilbene and its derivatives are able to form capping with DNA, making them very important covalent linker with DNA terminus to increase the fidelity of DNA duplexes as oligonucleotide hybridization probes. TMS-DNA structure is one of the most stable one among various kinds of stilbene-DNA structures. We study photo- induced transitions of stilbene and its derivatives and the change of vibrational spectra as a result of these transitions. All derivatives have vibrational frequencies in the THz region with a large difference in frequencies between two isomers. TMS-DNA structure, (TMS-TGCGCA)2, is optimized. The oscillator strength against frequency characteristics for both cis-TMS capping with DNA and trans-TMS capping with DNA structures is determined.
