Resonances

Some articles on resonances, resonance:

Methylcyclopentadiene
... For example, (MeC5H4)Fe(PPh3)(CO)I, exhibits four MeC5H4 resonances in its 1H NMR spectrum and five MeC5H4 resonances in the 13C NMR spectrum ... complex (MeC5H4)Fe(CO)2)I exhibits only two MeC5H4 resonances in the 1H NMR spectrum and three MeC5H4 resonances in the 13C NMR spectrum ...
Secular Resonance
... A secular resonance is a type of orbital resonance ... Secular resonances occur when the precession of two orbits is synchronised (a precession of the perihelion, with frequency g, or the ascending node, with frequency s, or ... A small body in secular resonance with a much larger one (e.g ...
Resonant Trans-Neptunian Object - Known Populations - Other Resonances
... So called higher-order resonances are known for a limited number of objects, including the following numbered objects 45 (35 AU, ~205 years) (131697) 2001 XH255 34 (36.5 AU, ~220 years ... few objects are known on simple, distant resonances 13 (62.5 AU, ~495 years) (136120) 2003 LG7 14 (76 AU, ~660 years) 2003 LA7 15 (88 AU, ~820 years) 2003 YQ179 (likely coincidental) Some notable unproven (they ...
Room Modes
... Room modes are the collection of resonances that exist in a room when the room is excited by an acoustic source such as a loudspeaker ... Most rooms have their fundamental resonances in the 20 Hz to 200 Hz region, each frequency being related to one or more of the room's dimension's or a divisor ... These resonances affect the low-frequency low-mid-frequency response of a sound system in the room and are one of the biggest obstacles to accurate sound reproduction ...
Schumann Resonances
... The Schumann resonances (SR) are a set of spectrum peaks in the extremely low frequency (ELF) portion of the Earth's electromagnetic field spectrum ... Schumann resonances are global electromagnetic resonances, excited by lightning discharges in the cavity formed by the Earth's surface and the ionosphere ...
