Experimental and calculated study of the vibrational modes of poly(dG-dC).poly(dG-dC) in B and Z conformations.
Infrared spectra of the B and Z forms of poly(dG-dC).poly(dG-dC) are presented. Experimental assignments relative to certain vibration modes have been confirmed by calculation based on the GF-Wilson method. The calculated results show that only the geometry change between B and Z forms, is responsible for the observed modifications in the vibrational spectra.
