involves the interaction of materials with the low-energy radio wave region of the EM spec
1 of 5
what is the use of TMS?
used as the standard in chemical shift measurements - at 0 (ignore it)
2 of 5
What is the need for deuterated solvents in NMR?
D is an isotope of Hydrogen/ to prevent solvents from producing unnecessary peaks on the spec as the solvents nuclei do not absorb any radio wave energy
3 of 5
How are N-H and O-H protons detected?
proton exchange using D2O - both have a very large range that can interfere with the other peaks/ run two spec 1 w/o d2o and now with - identifying the group

Where else is the NMR tech used?
in magnetic resonance imaging (MRI) used to obtain diagnostic information about internal structures
