Initial dimer axis

The direction of unstable vibrational mode can be obtained
by performing vibrational analysis (`IBRION`=5, see Sec. 6.22.6) and taking
the x-, y-, and z- components of the imaginary vibrational mode (after division by SQRT(mass)!) parallel with the reaction coordinate. Note that in order to plot "Eigenvectors after division by SQRT(mass)", `NWRITE`=3 should be used.
