Title: Electronic Spectroscopy (d-d spectra) - Term Symbols
Post by: xxangelxwingsxx on April 25, 2011, 12:18:34 PM

I'm a bit confused about working out term symbols for electronic spectra of d metal complexes. I know you can work them out using the cross products in group theory tables so:

d(1)=(t2g)1 = t2g
d(2)=(t2g)2=t2gxt2g=[t1g] ground state as it's a triplet.

But then how would you work out d(3)? t1gxt2g=a2+e+t1+t2 so which is the ground state?

Also what do these different term symbols actually represent? Is it different m(L) values?  ???
