vibrational analysis of interfacial water

[Phil G.]

Dear S. Ling,

I still don't see this problem, although the vibrational analysis 
was/should be performed only for the calculation of vibrational frequencies 
of water molecules in the system, not that of the crystal system. It is 
like as I would measure and obtain a vibrational spectrum of water at 
interface. 
Maybe the solution is to turn off the smearing method ?
I am new in CP2K and would appreciate some hints how to write input code 
enabling the calculation of vibrational frequencies of the interfacial 
water.

Kind regards,

Phil
