Problem P14B.5

Phenylalanine (Phe, 4) is a naturally occurring amino acid. What is the energy of interaction between its phenyl group and the electric dipole moment of a neighbouring peptide group? Take the distance between the groups as 0.4nm and treat the phenyl group as a benzene molecule. The dipole moment of the peptide group is $$\mu=2.7 \mathrm{D}$$ and the polarizability volume of benzene is $$\alpha^{\prime}=1.04 \times 10^{-29} \mathrm{~m}^{3}$$.
