Animate the Vibrational Modes.


orca_pltvib this program is used in conjunction with gOpenMol, wxMacmolplt or Chemcraft to produce animations or plots of vibrational modes following a frequency run. The usage is simple and produce a 20 frames of animation.

Remember that there are 3N-1 vibrational modes, so to check the number of the frequency you want to check, search in the output the VIBRATIONAL FREQUENCIES tag, and inspect the number of the frequency.
Isoprene molecule has 13 atoms so 39-1 vibrational modes.
grep -A 38 'IR SPECTRUM' *out #This will display in your screen all the vibrations.

orca_pltvib file.hess #freq #Generates the .xyz to see de vibration mode.

scp usr@server:/path/to/isoprene.hess.v017.xyz . #Download the xyz animation to visualize in wxmacmolplt.
[usr@server]$ ls
