Internuclear axis of asymmetric axis

[ajayguhan]

I understand internucler axis is a imaginary line about which the molecule rotates.and it's symmetric about the internucler axis.

So we can find the internucler axis by symmetry if the moecule is symmetric about some axis.



How would we find the internucler axis if the molecule is asymmetric about all the axis...?




Any help appreciated.thanks in advance.

Doesn't sound to me like "internuclear" has anything to do with rotation nor symmetry, name suggests just a simple geometry - line that goes through two nuclei.

It _may_ happen that internuclear axis is an axis of symmetry, it _may_ happen that molecule rotates around it, but logic tells me these are rather exceptional situations, limited to some small and simple molecules.
