15.3.3 1H NMR spectra index:
PLEASE READ THE
FOLLOWING 9 POINTS CAREFULLY
(and bear in mind this
is a pre-university chemistry website)
- I have included some alternative names and 'old names'
(still in common use - including mine and other internet databases),
BUT, DO NOT USE 'OLD
NAMES' IN EXAMS and ANY OF YOUR ACADEMIC WORK, without good
reason!.
- Most spectra described and interpreted were obtained with the
sample dissolved in CDCl3 solvent (trichloromethane in which the
1H atom has been substituted by a the 2H isotope -
hydrogen-2 or deuterium).
- In terms of spin-spin coupling from the possible proton magnetic orientations
I
have only considered the interactions of protons on adjacent carbon atoms
e.g. -CH2-CH3, protons
etc.
- BUT NOT e.g. CH3-O-CH2 or CH2-CO-CH3,
where the protonated carbons are separated by an atom NOT bonded to any
protons, and there are also interpretation problems with alcohols.
- AND at pre-university level,
I've assumed that equivalent protons
next to each other (same carbon atom or adjacent carbon atoms) in the same chemical environment will
NOT split each others NMR
resonance signals.
- ALSO, at pre-university level, assume N-H and O-H
protons do NOT normally cause splitting and neither are they split by
adjacent protons, this is due to the rapid exchange of protons between
the molecules e.g. OH protons in alcohols and carboxylic acids or NH
protons in amines or amides.
- At pre-university
level I have ignored spin-spin coupling resonance lines due to
1H
and 13C interactions or 13C and 13C spin
interactions and any other atoms capable of producing NMR resonances.
-
Chemical shifts are a set of relative
values, usually based on the
reference standard
tetramethylsilane.
- Si(CH4)4, which
has 16 protons in an identical molecular/chemical
environment.
-
TMS gives a
single sharp
reference signal significantly different in frequency from those
emitted from most 1H nuclei chemical environments of interest to
chemical structure investigations.
- At university level, points 3 to 7 may have to be re-considered and
taken into account when interpreting 1H NMR spectra.
