Orgo 2 exam 2

Chemical Shift Difference (ppm) between the resonance frequency of the proton being absorbed and that of TMS
Down Field Lower value of the applied magnetic field, toward the left on the NMR spectrum, the more DESHEILDED a nucleus is, the farther down field it absorbs
Upfield Higher value, toward the right, more sheiled a nucleus is, the farther upfield it absorbs
Complex splitting Splitting by 2 or more different kinds of protons w/ different coupling constants
Integration measurement of the area under a peak, proportional to the # of protons giving rise to that peak
Multiplet group of peaks resulting from the spin-spin splitting of the signal from a single type of nucleus
Desheilded Bonded to a group that withdraws part of the electron density from around the nucleus
Sheilded Surrounded by electrons whose induced magnetic field opposes the externally applied magnetic field
TMS Tetramethylsaline, an NMR standard absorption...0.00
MRI Medical term for NMR, avoiding the term nuclear. Use of field gradients in a large bore magnet to scan 2-D slices of the patient's body
