What do i and j stand for here? My teacher substituted them for masses (in our example, atoms in a molecule) although I'm not sure that makes sense since when you take the Hessian force constant matrix (on the next page of the link) I believe it must have dimensions determined by the number of degrees of freedom. In other words, for a two mass system (diatomic) wouldn't you have a 6x6 matrix? Is this correct? Again, what do i and j stand for?(adsbygoogle = window.adsbygoogle || []).push({});
