10 cards from this deck
TMS (tetramethylsilane) at δ=0\delta = 0δ=0 ppm
No. of environments, types, relative nos., adjacent H
Protons in same chemical environment, absorb at same δ\deltaδ
Look for planes of symmetry in the structure
Relative numbers of each type of proton
nnn adjacent H give n+1n+1n+1 peaks in splitting pattern
Singlet (1 peak)
Triplet (3 peaks, ratio 1:2:1)
Broad peaks, variable shifts, no spin-spin coupling
OH and NH peaks disappear from spectrum
