d8 isss what geometry
square planar
why is d8 square planar
u stretch out the z axis,, lowering any orbitals with a in them in energy.
the z^2 and the dxy overlap
what’s the delta values for square planar
1.2
0.2
-0.4
-0.5
the CFSE can also be called what
the driving force for a reaction
aka the energy needed for it to occur
if there’s a large CFSE what does that mean
it’s most probs gonna be square planar bc there’s a high driving force for i to be square planar
if we have a large CFSE ,, what do we not care about
we don’t care about P aka pairing energy bc delta is already large. meaning the driving force is already large
square planar can also be called
D4h
in d4h aka square planar how many transition do u get
u get 1 transition
in d4h aka square planar how many energy levels do u have
u have 7 energy levels aka y should have 6 transitions
what one trnaisitoon do we see for d4h
the dxy to dx2-y2
in d3 and d8 the first transition energy is
delta
in d2 and d7 delta is
v3-v1
in d5 spec what do we see
we see many weak but sharp dd spin forbidden transitions
weak bc break larporte rules
sharp bc doesn’t depend on delta??
