Additional weak SWNT absorption bands are observed, overlapping in part with the 6T band. Figure 2: Absorbance and Raman spectra of SWNTs, 6T, 6T@SWNTs and 6T@f-SWNTs.

Figure 2: Slight local deformation in a SWNT due to tip-applied pressure is sensed by means of Raman spectra. When a sample is pressurized by the tip, there is a risk of damaging the sample by ...

A lot of analytical methods have been implemented to elucidate the structure of SWNT materials. These vary from observational techniques like SEM, TEM, AFM and STM to spectroscopic techniques such as ...

There are three areas of the Raman spectrum of significant interest for SWNTs. The radial breath mode (RBM) from approximately 120 to 300 cm-1 is distinct to SWNTs and can be utilized to identify tube ...

An international research team has successfully achieved single-molecule spectroscopic observation of hydrogen (H2) and ...

Over the last decade Raman spectroscopy has become established as a physicochemical technique for the rapid identification of microbes. This powerful analytical method generates a spectroscopic ...

Fluorescence and Raman spectroscopy have become indispensable tools for non-invasively monitoring biological processes. Both methods rely on a stimulus light source, usually a laser, to excite either ...
