| Abstract | The LiP infinite double-helix chain gives us the unique opportunity to investigate the double-helix structure at atomic level. Based on density-functional theory, we investigate the characteristic vibrational modes of this peculiar structure. Differently from single-wall carbon nanotubes, a dipole mode in LiP gives rise to high infrared intensity. Owing to the peculiar double-helix structure of LiP, the frequency of the out-of-phase radical breathing mode is lower than that of the in-phase one. It is similar to the condition of DNA. Furthermore, the out-of-phase breathing mode in LiP, instead of the in-phase one, has the highest Raman intensity. Most importantly, our finding is generally applicable to other double-helix structures. Copyright (C) EPLA, 2014 |
