[CP2K-user] [CP2K:16612] Re: TRAVIS for IR spectra

[Sam Broderick]

Hi Sumit
Not really sure what you are asking. The really large values are the 
integral of the middle column, so it's not surprising that it's a big 
number.
It's the spectrum column (middle one of three) vs. wavenumber that would be 
the IR spectrum.

Sam
