✦ Synopsis

The electronic properties of purified carbon nanotube (multicylinder structure with an outer diameter of z 20 nm and a length of z 10 pm) was first examined based on the electron spin resonance (ESR) spectroscopy. By the Raman scattering measurement, only one peak at 158 1 cm-1 similar to that of graphite was found. The purified nanotube was almost ESR silent as well as the K-and the Iz-doped samples. This indicates that the purified nanotube examined in the present study is a 'clean' semiconductor almost without magnetic impurity and is doping inactive.

Atomic models of two single joints connecting (a) (9, 0) to (5, 5) and (b) (10, 0) to (6, 6) nanotubes have been constructed and relaxed on the computer using a molecular-mechanics model. Each connection is based on a pair of diametrically opposed pentagon and heptagon which bend the structure. The
