13C NMR Spectroscopy - Year 13 Chemistry
year13chemistrykbhs.weebly.com13C NMR spectroscopy The position of the peak in a 13C NMR spectrum is determined by the shielding or deshielding effects of other atoms around it. The less electrons (ie the more electronegative atoms around the carbon) the higher magnetic field the nucleus is exposed to, hence it is harder to flip and the ppm value is higher.
Gamma Ray Spectroscopy - University of Michigan
www-personal.umich.eduThe photoelectric absorption interaction is the ideal interaction for gamma-ray spectroscopy. The photoelectron carries away most of the gamma-ray energy and then an X-ray or Auger electron carries away the remaining kinetic energy. Assuming an ideal detector, the sum of these energies will equal the energy of the original gamma-ray.
