a
For those hydrogens shown as , if that hydrogen is part of a methyl group (CH
3
) the shift is generally at the low
L

L
end of the range given, if the hydrogen is in a methylene group (ICH
2
I) the shift is intermediate, and if the hydrogen is in
a methine group ( ) the shift is typically at the high end of the range given.
b
The chemical shift of these groups is variable, depending not only on the chemical environment in the molecule, but also
on concentration, temperature, and solvent.
