Chapter 13: NMR Spectroscopy
NMR is the most powerful tool available for
organic structure determination
NMR spectroscopy uses
radio waves
number of signal means
number of chemically unique H's in the molecule
chemical shift
the types of H's that are present
spin-spin splitting
the H's proximity to each other
what is a proton deshielded by?
the presence of a more electronegative atom (e.g oxygen and nitrogen)
the number of signals shows
how many different kinds of protons are present
the location of the signals shows how
shieled or deshieled is the proton
signal splitting shows
number of protons on adjacent atoms
downfield
movement toward the left in an NMR spectrum
upfield
Movement to the right in an NMR spectrum
the chemical shift of H depends on
