very straightforward:
1. create one atom selection for each residue and store
its name in a variable each.
2. call measure center with it (this can be
mass weighted or by other properties) and
store the resulting vector in a variable each
3. compute the distance between the two
vectors via veclength/vecsub.
for details check out the VMD users guide.
