Raman spectra of single-wall carbon nanotubes produced in the channels of zeolite AFl single crystals have been analyzed in the light of the full symmetry group, the line group. The phonon dispersion curves of the tubes (5,0), (3,3), and (4,2) are calculated based on the lattice dynamical model and the phonon branches are assigned to their quantum numbers (irreducible representations). The structures of Raman spectra of different samples are reproduced well by the density of states of relevant Raman-active phonons. The result is useful to evaluate the contents of these tubes in real crystals where the contents are not well defined before.

    An inside space of the single-wall carbon nanotube (SWNT) can be used as a template for one-dimensional molecular crystals simply by filling the space with molecules. Here we show some results of the filling with fullerenes, organic molecules, and DNA. High-density filling was confirmed by X-ray...

    By annealing fullerene peapods at high temperatures in a dynamic vacuum it is possible to produce double-wall carbon nanotubes. A Raman investigation revealed that the inner single-wall carbon nanotubes are remarkably defect free showing very strong and very narrow radial breathing modes (RBMs)....

    Recently, it was possible to fill single wall carbon nanotubes with C[SUB60] fullerenes resulting in carbon structures with new and interesting properties (so-called C[SUB60] peapods). All Raman allowed modes of the free C[SUB60] were identified for the encaged C[SUB60]. In this contribution we...
