In the first study of its kind, we previously investigated Raman spectra of 17 papyri from the Columbia University Libraries collection, written in carbon-based black ink with well-established dates between 400 BCE and 1000 CE. Using a simple two-peak spectral model for the Raman spectrum of ...

Raman spectra were recorded from multiple points on both traces, Figure 3b. While both traces share some Raman signatures (orange peaks), there are significant differences. Trace 1 has several unique signatures (green peaks), and the intensity of certain bands differs between the traces. For ...
RamanStation 400产品说明书 In modern dispersive Raman spectroscopy, good quality spectra can be obtained from the majority of typical samples. These spectra show sharp, well-defined peaks with, in most cases, a relatively flat, noise-free baseline. In some cases, however,laser-induced fluorescence...

Although the literature on the Raman spectra of carbon fibers is vast, no consistent, robust predictive relationship between mechanical properties of carbon fibers and spectral parameters exists. This shortcoming is due to the use of numerous fitting functions to evaluate Raman spectra of carbon fibers...

A Microsoft Excel® spreadsheet was used to process un-deconvolved spectra (Fig. 1a) by performing smoothing operations, baseline corrections and normalization, to acquire the height and position of the saddle height, D1 and G band, G-FWHM, D-FWHM and areas of specific regions using the ...
