||Single wall carbon nanotubes (SWCNs) of mono size and unique chirality are fabricated by pyrolysis of tripropylamine (TPA) molecules. These SWCNs are confined inside the 1 nm-sized channels of zeolite AFI crystal. Micro-Raman scattering of these SWCNs is done and the specific radial-breathing mode which is unique for carbon nanotubes are observed. Also, Alg, Elg, and E2g, vibration modes are identified. Furthermore, the UV-visible absorption spectrum of these nanotubes is also measured. A broad absorption band with a center energy at 3.7 eV is being observed, which is attributed to the inter-band transition of the one-dimensional nanotube. This result agrees well with the band structures calculated using the tight binding model.
