Dear origin experts,
How are you? My name is Zin. I have a trouble with Fourier Transformation.
I have a data, and I would like to do the Fourier transformation, but the X-axis is weird after FT.

Actually, my data is the same to the figure 2 in attached file (J. Chem. Phys. 111, 6238 (1999); doi:10.1063/1.479928), and my data should be Fourier transformed like the figure 5. However, X-axis is not the same...
Can you help me with this problem?
Hopefully,

Hi Zin,
You cannot attach files, can only upload pictures, to this forum. The journal you refer to:
J. Chem. Phys. 111, 6238 (1999); doi:10.1063/1.479928
we cannot access.
So either post pictures of the figures you are quoting here, or send the figures/pdf of article, to tech support so we can look.
See link on top right of forum page on how to "Send File to Tech Support"
