* Emission spectroscopy is a spectroscopic technique which examines the wavelengths of photons emitted by atoms or molecules during their transition from an excited state to a lower energy state. Each element emits a characteristic set of discrete wavelengths according to its electronic structure, by observing these wavelengths the elemental composition of the sample can be determined. * Absorption spectroscopy measures the loss of electromagnetic energy after it illuminates the sample under study. For example, if a light source with a broad band of wavelengths is directed at a vapour of atoms, ions, or molecules, the particles will absorb those wavelengths that can excite them from one quantum state to another.
ICP-AES stands for: Inductively Coupled Plasma - Atomic Emission Spectroscopy. ICP-OES stands for: Inductively Coupled Plasma - Optic Emission Spectroscopy. They are the same technique, just different names for it.
Raman scattering involves the SCATTERING of electromagnetic radiation by molecules, not atoms Fluorescence emission follows an absorption process
I'll try to help you out: The difference between absorption and scrubbing process as regards what?? We don't know what you are talking about - not enough information!
Wicking is a kind of absorption, in which capillary pressure is the only cause. The absorption may happen by external pressure and/or capillary pressure.
The difference between continuous spectrum and the atomic emission espectrum of an element is that in emission spectrum, only certain specific frequencies of light are emitted while in a continuous spectrum, a continuous range of colors are seen in the visible light.
The acronyms are synonyms. AES = Atomic Emission Spectroscopy OES = Optical Emission spectroscopy
Source modulation is employed to distinguish between atomic absorption (an ac signal) and flame emission (a dc signal).
Emission is something be spread out, while absorption is something being taken in.
ICP-AES stands for: Inductively Coupled Plasma - Atomic Emission Spectroscopy. ICP-OES stands for: Inductively Coupled Plasma - Optic Emission Spectroscopy. They are the same technique, just different names for it.
Emission spectrum: lines emitted from an atom.Absorption spectrum: absorbed wavelengths of a molecule.
I dont know why did you think i ask wiki answers duhhh.................
LCR meter is a device. And electrochemical impedance spectroscopy is a method. So the difference between them are like the difference between pen and writing.
The lines are at the same frequencies
Raman scattering involves the SCATTERING of electromagnetic radiation by molecules, not atoms Fluorescence emission follows an absorption process
Absorption spectrum is a gap in the overall spectrum. It happen when light makes an electron jump to a higher orbital and light energy is absorbed. Emission spectrum is light emitted at particular wavelengths (where the absorption spectrum gaps are). It happens when an electron falls from a higher orbital and emits light energy in doing so.
stimulated emission causes due to the energy difference between the higher and lower energy level state, but it doesn't depends in the case of spontaneous emission . spontaneous emission causes without any stimulation .In stimulated emission energy transfer is twice the energy transfer of spontaneous emission.
