Problem E14B.2(b)

Use eqn 14B.3b to calculate the molar potential energy of the dipolar interaction between an amide group \((\mu=2.7 \mathrm{D})\) and a water molecule (\(\mu=1.85 \mathrm{D}\)) separated by 3.0 nm with \(\theta=45^{\circ}\) in a medium with relative permittivity of 3.5.

Text Transcription:

mu=2.7 D

(mu=1.85 D)

theta=45^circ
