Description

Some Electrical and Optical Aspects of Molecular Behaviour deals with dipole moments, molecular science, and molecular polarizability. The author explains the refractive index and the electric permittivity including polarization, polarizability, the Mossotti-Clausius equation, molar polarization, and molar refraction. The author also addresses the results of dipole moment measurements, the significance of the values obtained, and how these can determine molecular structural features. By using the Debye equation, one can determine the molecular moments of polar solutes in non-polar solvents. The book discusses how molecular polarizability and molecular polarization are measured and how these factors are associated with molecular structure. He also explains light scattering and the molecular weight of solutes by employing the research made by Debye which determines the weights, shapes, and interactions of molecules in solution. The author also addresses the form and order of the magnitude of interaction energies and cites typical examples of these occurrences. These energies often represent an electrostatic nature; in some ways, they can be understood as being quantum-mechanical in nature. This book can be helpful for students taking up dipole moments, molecular polarizability or molecular science.
