Thanks for reply.
Here are more details about my simulation.
I have glucose molecule in my system. I am interested in change in dipole
moment of OH bond of glucose along the simulation.
The OH group is not neutral so your dipole is meaningless (position
dependent).
Otherwise the charges are constant and the fluctuation in bond length
(if you have a flexible molecule) will be small, or zero with
constraints. You should think what you want to get out. What experiment
you want to compare to.
I have made the index file.
How can I select two groups (oxygen and hydrogen) or should I put
particular oxygen and hydrogen in same group (manually).

Hello,
Can I calculate a dipole moment of a particular bond?
It is easier to do it manually. Otherwise g_dipoles with a suitable
index file would do it. The sum of charges has to be zero of course.
I am using gromacs version 4.0.7.
Thanks
