摘要：

985 nm in the 380-500 cm(-1) region are described. These IFMs parallel behaviour previously observed at higher frequencies and resonance energies [Phys. Rev. Lett. 93, 087401 (2004); Phys. Rev. B 72, 085446 (2005)], but in the present case occur through coupling to transitions intermediate in energy between E,, and E-22. The IFM intensity behaviour on bundling is found to be the opposite of that for the radial breathing modes (RBMs). We demonstrate that exciton-phonon coupling for the IFMs is enhanced by the bundling process, while the opposite is found for the RBMs. (c) 2007 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
