This up-to-date account of key areas in modern organic spectroscopy describes the four major instrumental methods used routinely by organic chemists: ultra-violet/visible, infra-red, nuclear magnetic resonance spectroscopy, and mass spectroscopy. It provides a concise introduction to the physical back...
to the synthetic organic chemist but is also of use to biochemists for investigating the solution state structure and function of proteins, enzymes, etc. The application of high resolution NMR to the solid state is also discussed, thereby indicating the developments which have taken place as far...
Introduction to Magnetic Resonance Spectroscopy ESR, NMR, NQR Spectroscopy in general and magnetic resonance spectroscopy in particular is a vital tool for the identification and structure determination of organic and inorganic molecules. Though magnetic resonance spectroscopy was discovered by phy... AN ...

Several manuscripts discuss the synthesis of small organic molecules containing diphenylmethylene, carbazole and malononitrile units, and polymers and how their AIE properties are used for cell imaging [38, 39]. The aim of this Focus Issue is to provide a platform for interdisciplinary researchers ...

Organic geochemical indices and biomarkers show that the Opalinus Clay in the Mont Terri section is thermally immature, having experienced maximum burial temperatures of about 80 °C during Cre- taceous burial (Mazurek et al. 2006), and shows low hydrocarbon source-rock potential. 2.4 Other key...
The E,E-configurations of the 2,6-dimethyl groups of 1 were confirmed by two-dimensional rotating-frame nuclear Overhauser effect spectroscopy (ROESY)22–24. These experiments showed no cross-peaks between methyl protons at C1 and C7 positions (7.61 ppm), i(nHdai)caattinCg2 and that C6...

When excited by high energy (short wavelength) photons, most organic molecules will tend to fluoresce. Although fluorescence is usually considered to be a low light level process, it can still overwhelm the signal in the Raman spectrum (Figure 5). This is because the Raman effect contains a ...
