Normally,
the
n+1
rule
applies
where
the
signal
 contains
 perfect
 overlap
 to
 generate
 a
 doublet,
 triplet,
 quartet,
 etc.
 
 When
 these
 protons
 are
 different,
 each
 proton
 splits
 the
 NMR
 signal
 of
 the
 other
 so
 that
 each
proton
appears
as
a
doublet.

For
example,
if
you
draw
a
doublet
of
doublets,
 and
bring
the
signals
close
together,
they
overlap
to
constructively
create
a
triplet.

 Simply
 stated,
 a
 triplet
 is
 a
 doublet
 of
 doublets
 where
 two
 of
 the
 signals
 overlap
 perfectly
to
make
a
tripl...
