1
Q
How to calculate speed of light?
A
c=λv, λ-wavelength inn m, v- frequency in Hz
2
Q
How to calculate wavenumber?
A
1/wavelength
3
Q
What is the symbol for wavefunction?
A
g
4
Q
What is the Born-Oppenheimer Approximation?
A
Owing to the difference in mass between the elctron and nuclei, the motion of the two may be separated and the total wavefuntion may, to a good approximation, be written ψtot=ψelψnuc
5
Q
To what ψnuc can be factorized?
A
To ψvib ψrot
6
Q
In what range elctronic transitions happen?
A
500-100 nm, visible- ultraviolet region
7
Q
In what range vibrational transitions happen?
A
8
Q
In what range rotational transitions happen?
A
10cm-1mm, microwave region
9
Q
What is Boltzmann law?
A
At thermal equilibrium, the relative population on the ith energy level is given by
