CD/helix/hydrogen bond

I need to understand the theory behind CD a little better:

Is the hydrogen bond itself important for the CD spectrum of an alpha-helix 
in a protein? Or does the signal only depend on bond angles? So the 
(hypothetical) question is:
Would an alpha helix which has the correct angles but NO hydrogen bonds 
give the CD spectrum of a native hydrogen bonded alpha-helix?
