- Question is regarding spectroscopy: What are the units of %T? What are the units of absorbance?A nucleus that is deshielded will appear in the NMR spectrum. A) downfield B) upfieldthe shielding in NMR is: a) Place a metal around the sample tube before staining it on the instrument.b) use a metal block to avoid being attacked by an opponentc) blocking the view of a participant in a concertd) when the magnetic moment of an atom blocks the induced magnetic moment of neighboring nuclei
- help with my organic chemistry homework please. these 2 questions go together you have to answer the one with the NMR spectrum first to answer the second oneNeed help annotating IR spectrum peaks3. Which spectrum would be predicted from ? (Assume coupling constants are equal. Use chemical shift and multiplicity information. Ignore relative intensities.) Select all that apply.
