 Dear all,

I want to measure the bond lengths during stretching and bending vibrations. I was reading about 
CRYSTAL23, and I learned that I can extract the eigenvalues of the vibrational modes, which would 
allow me to calculate the displacement of each atom during each motion. These eigenvalues can be 
found in the output file F10, as I read recently ?
