It's not clear what information you are looking for, or where the term
"molecular frame" comes from. You can use ptraj or carnal to superimpose
snapshots of an md simulation onto a common "frame", pretty much removing
overall translation and rotation. Analysis of such superimposed snapshots
would then be said to be in a "molecular frame".

..hope this helps...dac
