Spectroscopy - Spectroscopy - Applications: Spectroscopy is used as a tool for studying the structures of atoms and molecules. The large number of wavelengths emitted by these systems makes it possible to investigate their structures in detail, including the electron configurations of ground and various excited states.
Spectroscopy also provides a precise analytical method for finding the. Spectroscopy is the study of the interaction between matter and electromagnetic radiation as a function of the wavelength or frequency of the radiation.
Historically, spectroscopy originated as the study of the wavelength dependence of the absorption by gas phase matter of visible light dispersed by a elementary description of absorption, emission and scattering spectroscopy. Spectroscopy, study of the absorption and emission of light and other radiation by matter, as related to the dependence of these processes on the wavelength of the radiation.

The latter part of the book describes optical measurement techniques and equipment. In the study of SWCNTs, PL spectroscopy is widely used. However, it is difficult for PL spectroscopy to characterize m-SWCNTs which do not fluoresce. The overlapped spectral features in simple emission or absorption spectra are clearly separated in 2D excitation-emission spectra so that it is quite suitable to identify the sc-SWCNTs .
