hi
i have two questions , that i cannot solve by my own:
does anybody know how to calculate the potential energy of two quadrupole moments that are separated by a distance r?( i looked for it in all my physics books, but i did not find anything at all)
and: if you have two dipoles there is an equation for the potential energy that varies with the distance 1/r³ but what exactly does this distance 1/r³ between the two dipoles mean?
for example: if you think of two hydrogen atoms, that possesses a dipole moment, that is caused by an electric field. then what is this distance 1/r³? is it just the distance between the two nuclei or do you have to take account for the fact, that the electron is not in a spherical symmetric orbital anymore if there is an electric field and 1/r³ is some kind of mean value between the electron position and the nucleus of the one atom to this point at the other atom?
