Electronic Soectrospcy Flashcards
1
Q
What is electronic spectroscopy
A
How em radiation interacts with a molecule to change its electronic energy
2
Q
How are the energy levels spaced
A
Widely in the UV bus region
3
Q
What is the gross selection rule
A
Change in dipole as electron moves
4
Q
What does the specific molecule determine
A
MO involved e.g. Energy gaps - absorption wave lengths and band strength are E values
5
Q
What transfers have grown peaks
A
Charge and pi to pi *
6
Q
Why are several bands seen in the spectrums
A
Several MOs are involved
7
Q
What effect does conjugation have on energy gaps
A
Decreases
8
Q
What is electronic spectroscopy used for
A
Quantitative analysis and electronic structure
9
Q
What is an isosbestic point
A
The constant absorbance at a specific wavelength as 2 species interconvert
