RBM frequency 怎么計算?
|
|
最近看文獻(xiàn)看到一個參數(shù):RBM frequency( radial breathing mode frequencies)不明白什么意思,兩個問題: 1、RBM frequency 是描述什么性質(zhì)的一個參數(shù)? 2、怎么計算這個參數(shù)? 不太了解,有點(diǎn)好奇,望各大神不吝賜教! |

| Raman spectroscopy is a powerful tool for the characterization of the SWNTs. One of the interesting features in the Raman spectrum of the SWNTs is the appearance of the radial breathing modes (RBMs), whose frequencies depend on the diameter of the SWNTs. This dependence has been expressed as fb= 223.75/d, where fb is the frequency in cm-1 and d is the diameter of the SWNT in nm.--采用raman技術(shù)來表征單層碳納米管(Single-Wall Carbon Nanotube),可以算出碳納米管直徑d....... |
