Nuclear magnetic resonance (NMR)
spectroscopy can be used to gather information about the structure
of a compound. The chemical shift of peaks in a 1H NMR or a 13C NMR
spectrum can be used to gather information about the types of
neighboring functional groups. The spin-spin splitting pattern in a
1H NMR spectrum can be used to determine the number of hydrogen
atoms on neighboring carbon atoms.
The chemical shift (?) of an atom is influenced by the
electrons...

Proton (1H) NMR spectroscopy can provide which of the following pieces of information? (More than one choice may be correct.) Select one or more: a. The number of hydrogens that correspond to a given signal. b. The degree of unsaturation present in the molecule. O c. The number of unique hydrogens in the molecule. d. Information concerning the type of chemical environment for each hydrogen signal. e. How many hydrogens are on adjacent carbon atoms. f. The molar mass of...
