Dear Juerg,

Thank you so much for your reply. 
I am not finding anywhere printing the vibrational frequency. 
My aim is to find the infra-red spectra  of water molecule. I have 
calculated the total dipole moment of the system  using reference as COM. 
But the fourier transform of the total dipole is not giving the right IR 
spectra. 
I will also like to  know what delta_dipole mean which is also printing 
with total dipole. 

Thank you so much
