Dear Netters:
i would like to know what is the true definition of bond, this question can also be given in the following:
given a file only including coordinates of atoms in molecule, there are not connectivities between atoms in molecule, just from 
this file how can i find the bonds or connectivities? using Van der walls radius or covalance radius of atoms or some results of 
population analysis from theoretical calcualtion?

thank you
