2017426 · Infrared (IR) spectroscopy is a physical science on molecular vibrations, with which the molecular characters can be discussed in detail. The molecular characters are represented by the molecular conformation, hydrogen bonding, crystallinity, and orientation as well...
view moreNormal Vibrations and Friction Under Harmonic Loads: Part I—Hertzian Contacts. Nonlinear vibrations at a Hertzian contact are studied by the perturbation technique known as the method of multiple scales. As a result of the nonlinear Hertzian stiffness, the average normal contact deflection during oscillations is smaller than the static ...

view moreNormal modes, as implied by their name, are orthogonal to each other. In order to discuss the quantum-mechanical equations that govern molecular vibrations it is convenient to convert Cartesian coordinates into so called normal coordinates. Vibrations in polyatomic molecules are represented by these normal coordinates.
