Hi Lalitha, Zebularine is beyond the trivial. You may be able to derive something reasonable from the other bases using 'chemical intuition' (cytidine, thymidine, uracil), but it's likely that the electronic structure of the ring is too different to justify an approach like that. Likely you should perform parameterization the proper way, which is not a beginners subject. At least have a look at http://www.gromacs.org/WIKI-import/Parametrization
