Electronic Structure Flashcards
1
Q
How do you calculate spin multiplicity?
A
S=2(Ms)+1
Where
Ms= sum of e- spins
2
Q
What is ML
A
ML=sum of mL
where mL is the sum of the states
3
Q
What are selection rules for uv-vis spectroscopy?
A
transition moment must not be equal to 0
spins cannot flip during transitions
4
Q
why is the frequency of a transition not related to the absorbance?
A
Absorbance is a measure of liklihood
Frequency is a measure of energy
5
Q
describe the these values for the extinction coefficient
<1
~100
~250
>1000
A
<1 - Spin Forbidden
~100 - d-d laporte Forbidden
~250 - d-d laporte Allowed
>1000 - Fully Allowed
