a strong sharp peak
at 1577.7 cm-1 (G line), which can be assigned to the
high-frequency E2g first-order mode, and a strong sharp
peak at 1349.9 cm-1 (D line) as well as a weak peak,
appeared as a shoulder peak of G line, at 1612.9 cm-1
(D¢ line). The origin of the D and D¢ lines has been
explained as disorder-induced features due to the finite
particle size effect or lattice distortion of graphite
crystals. Therefore, the very strong relative intensity
of the D line may be the result of a
high lattice distortion of graphite crystals in the HCNTs.
The weak peak at 1099.0 cm-1 was rarely reported
previously. The peak at 2447.0 cm-1 was frequently reported
previously, but the origin of it remains uncertain.
Here, the peak 2447.0 cm-1 seems to be the combination
of D line and the peak 1099.0 cm-1 (1349.9 + 1099.0 )
2448.9).

多壁碳纳米管:大约1350 cm-1 处一个    1580cm-1左右一个     峰会分裂
单壁碳纳米管:200cm-1 处左右有几个峰  1350 cm-1 左右一个    1580cm-1左右一个
管的质量较高时 1350 cm-1处的峰会较低。

有时峰会有一些偏移,如在1350cm-1处没有,而在1344cm-1处有,但偏移不会很大
