How to model HCN gas molecule by NAMD?

Hi all. I just have this short question. How to model HCN gas molecule by NAMD?
 HCN is a very polar molecule with positive and negaive charges at its two ends. When I start the simulation, the gradient of the force is too large probably due to the electrostatic attraction between its two ends. The angle force constant is too small, as the H-C-N angle in this case is rigid.
 Thanks for all your time!
