Subject: freezing atoms in frequency calculations

Dear all,
I wonder if there is an ab initio code that lets one freeze all atoms 
but one in a large molecule, and calculate the frequency related to the 
atom which was not not frozen, say, like calculating the frequency of a 
single OH stretch in some molecule?
Thank you in advance!
