UT theoretical chemistry code forum

Hi,
I'm having a fundamental question here. Please correct me if I'm wrong.

D=(a^2)*(Equilibrium concentration of vacancies)*(defect jump Rate).
Empirically it is given as D = Do * exp (-Q/KbT)
And all the temperature independent terms are clubbed together into Do.

Priya, I think the exp(dS/Kb ...

Oh, I got it. Thank you very much.

However, two different definitions of wavenumbers are there.
How is it defined here? Is it 1/wavelength, or (2*pi)/wavelength ?

Hi,

I was just wondering why is the Unit of frequencies obtained from the DynMat calculations in cm ^-1?
Shouldn't it be in units of time ^-1, ie second ^-1 or Hz ?

Thanks..
