Oscillation in chemistry
WebThe Belousov–Zhabotinsky (BZ) oscillating chemical reaction involves the oxidation of an organic compound by the bromate ion in the presence of a metal ion catalyst such as cerium(iv), manganese(ii), or ferroin. Simple periodic oscillations are generally obtained for the BZ reaction in a batch (closed) system. Jump to main content A molecular vibration is a periodic motion of the atoms of a molecule relative to each other, such that the center of mass of the molecule remains unchanged. The typical vibrational frequencies range from less than 10 Hz to approximately 10 Hz, corresponding to wavenumbers of approximately 300 to 3000 cm and wavelengths of approximately 30 to 3 µm. For a diatomic molecule A−B, the vibrational frequency in s is given by , where k is the force con…
