d(GTCGAC)
2
in
the
absence
(A)
and
presence
(B)
of
0.75
equivalents
A-[Ru(phen)2dppz]2+
per
duplex.
Conditions
are
as
described
in
the
text.
The
H1'
NOE
walk
is
indicated
for
the
free
duplex.
Due
to
the
asymmetric
binding
of
the
metal
complex
under
slow
exchange
conditions,
the
H1'
NOE
walk
for
the
bound
duplex
is
less
apparent.

H20/10%D20.
A
jump
and

was
used
to
acquire
the
spectra.
The
broadening
and
upfield
shifts
of
the
resonances
with
the
addition
of
metal
complex
is
consistent
with
intercalation.
