dominant mode will be the mode imposing the maximum amplitude of the modal variable. A mode of vibration is characterized by a modal frequency and a mode shape

parts due to vibration modes caused by specific vibration frequencies. The most common types of vibration testing services conducted by vibration test labs

molecule has 3N − 5 modes, because rotation about the molecular axis cannot be observed. A diatomic molecule has one normal mode of vibration, since it can

combination modes of molecular vibrations. The mid-infrared, approximately 4,000–400 cm−1 (2.5–25 μm) is generally used to study the fundamental vibrations and

certain vibration frequencies, its natural frequencies, the surface moves in a characteristic pattern of standing waves. This is called a normal mode. A membrane

technique typically used to determine vibrational modes of molecules, although rotational and other low-frequency modes of systems may also be observed. Raman
