not part of compound, 0 ppm

right, upfield, shielded

For 13C-NMR and 1H-NMR, the more negatively-charged, the further to the _______________, the more _________________ and the more ____________________

left, downfield, de-shielded

For 13C-NMR and 1H-NMR, the more postively-charged, the further to the _______________ , the more ________________ and the more _____________________

integral numbers in 1H-NMR

tell how many hydrogens are in that peak

splitting for 1H-NMR

count all H next door in all directions, and add one. (n + 1 rule)
