Whats people lookup in this blog: In nuclear magnetic resonance (NMR) spectroscopy, the chemical shift is the resonant frequency of a nucleus relative to a standard in a magnetic field. Often the position and number of chemical shifts are diagnostic of the structure of a molecule.

5 Jan 2011 Conversely, 1 ppm on a 200 MHz NMR spectrometer corresponds to: 1 x 10-6 x 200 x 106 Hz = 200 Hz 0 ~ 10 ppm (see Table 10.3 on p. 2 Summary Tables. 2.3 1H NMR Spectroscopy. Summary of the Regions of Chemical Shifts, δ (in ppm), for Hydrogen Atoms in Various Chemical Environments.

This ppm scale relative to TMS and the increasing value to the lower magnetic field (i.e., to the left from TMS) is called “the δ-scale.” The 1H peaks of most of the organic compounds fall in between δ = 0 ~ 10 ppm (see Table 10.3 on p. 361 of Ege’s book).
- Gli idrogeni legati ad atomi elettronegativi sono deschermati, quindi risentono di un più forte campo magnetico e hanno spostamenti chimici più alti. 2. - Gli elettroni π degli alcheni, degli anelli aromatici e dei carbonili, portano ad un aumento del campo

The types of protons present (δ = chemical shift is given in parts per million, the usual range = 0-10 ppm, a few chemical shifts extend to 10-15 ppm). 2. Prof Mauro Tonellato Tabelle di spettroscopia NMR Tabella B Calcolo degli spostamenti chimici Gli spostamenti chimici di CH3, CH2, e CH in un alcano sono 0,9 (CH3), 1,3 (CH2) e 1,7 ppm (CH). Nelle altre molecole, a questi valori vanno sommati gli ulteriori spostamenti dovuti all’intorno chimico.
