Vdw distances

  1. Jul 29, 2007 #1

    I am looking for table or something that gives a tumb of rule for van der Waals distances - I have some C C spatial interactions which I would like to determine if their interaction contributes to the total energy or should I calculate it with a Lennard-Jones potential to get an estimation?

    Any advise appreciated.
    Best Regards

    I would assume that one half of the bond length of the species of interest would be a close approximation.

    Can you give us a fuller description of the problem? C~C interactions have typical vdW strengths (10s of meV/atom) at separations of 30 to 50 nm.
