Dear Pwscf users,

Could you please tell me is it possible to solve a system with pwscf that is not periodic?

For example, I would like to calculate phonon frequencies of a molecule with a larg amount of atoms such as 500,defining this molecule 
in a periodic lattice is easy but its phonon caculation is impossilble here.
Does anybody have any solution? 
Any helps are appricated.

Bests
