Hi to everybody;

I wanted to ask: which is the factor of conversion from cm^{-1} to eV?

Thank you!

I'll ask this first so that you know where to look. Do you have Ashcroft and Mermin's "Solid State Physics" text? It is listed in the table on the inside back cover of the book.Hi to everybody;

A number I use is that 1=1.932 keV-Angstroms.

In optical conductivity area of study, it is very common to talk in inverse length to signify a corresponding energy scale. This is because from experiment, the value of "k" (either crystal momentum, electronic momentum, or wave number) falls out naturally from measurement.

That is because mine is for k=1/lambda, with k in cm^-1,

and AM is for p=2pi/lambda with p in cm^-1.

You have to decide whether you are using k or p.
