Specifically, electron or hole oscillations in DNA dimers (two interacting DNA base-pairs or monomers) are predicted, with frequency in the range f ~ 0.25 - 100 THz (period T ~ 10 - 4000 fs) i.e. potentially absorbing or emitting electromagnetic radiation mainly in the mid- and far-infrared with wavelengths ~ 3 - 1200 μm. The efficiency of charge transfer between the two monomers which make up the dimer is described with the maximum transfer percentage p\  and the pure maximum transfer rate pf. For dimers made of identical monomers p = 1, but for dimers made of different monomers p \< 1. The investigation is extended to DNA trimers (three interacting DNA base-pairs or monomers). For trimers made of identical monomers the carrier oscillates periodically with f ~ 0.5 - 33 THz (T ~ 30 - 2000 fs); for 0 times crosswise purines p = 1, for 1 or 2 times crosswise purines p \< 1. For trimers made of different monomers the carrier movement may be non periodic. Generally, increasing the number of monomers above three, the system becomes more complex and periodicity is lost; even for the simplest tetramer the carrier movement is not periodic.}, doi = {10.1002/andp.201400067}, url = {https://onlinelibrary.wiley.com/doi/full/10.1002/andp.201400067}, author = {Lambropoulos, K. and Kaklamanis, K. and Georgiadis, G and Simserides, C.} }
