Preresonance Raman spectra of methylpyridines
Journal of Raman Spectroscopy, 1990 AbstractPreresonance Raman spectra of methylpyridines (picolines) are presented for different incident laser wavelengths. A strong intensity variation of the non‐totally symmetric vibration 10α is observed, which implies a vibronic coupling of the lowest nπ* excited state with the next ππ* (B2u and B1u) states. In addition an intensity increase of some

Optical Absorption and Raman Spectroscopy Study of the Fluorinated Double-Wall Carbon Nanotubes [PDF]
, 2006 Double-wall carbon nanotube (DWNT) samples have been fluorinated at room temperature with varied concentration of a fluorinating agent BrF3. Content of the products estimated from X-ray photoelectron data was equal to CF0.20 and CF0.29 in the case of ...

Rapid identification of pathogenic bacteria using Raman spectroscopy and deep learning
Nature Communications, 2019 The use of Raman spectroscopy for pathogen identification is hampered by the weak Raman signal and phenotypic diversity of bacterial cells. Here the authors generate an extensive dataset of bacterial Raman spectra and apply deep learning to identify ...
