  2. Microwave chemistry - Wikipedia

    en.wikipedia.org/wiki/Microwave_chemistry

    Microwave-specific effects tend not to be controversial and invoke "conventional" explanations (i.e. kinetic effects) for the observed effects. [19] Non-thermal microwave effects have been proposed in order to explain unusual observations in microwave chemistry. As the name suggests, the effects are supposed not to require the transfer of ...

  3. Microwave spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Microwave_spectroscopy

    For insulating materials (both solid and liquid), [6] probing charge dynamics with microwaves is a part of dielectric spectroscopy.Amongst the conductive materials, superconductors are a material class that is often studied with microwave spectroscopy, giving information about penetration depth (governed by the superconducting condensate), [4] [7] energy gap (single-particle excitation of ...

  4. Microwave - Wikipedia

    en.wikipedia.org/wiki/Microwave

    Microwave is a form of electromagnetic radiation with wavelengths shorter than other radio waves but longer than infrared waves. Its wavelength ranges from about one meter to one millimeter, corresponding to frequencies between 300 MHz and 300 GHz, broadly construed.

  5. Electromagnetic spectrum - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_spectrum

    By definition, visible light is the part of the EM spectrum the human eye is the most sensitive to. Visible light (and near-infrared light) is typically absorbed and emitted by electrons in molecules and atoms that move from one energy level to another.

  6. Microwave digestion - Wikipedia

    en.wikipedia.org/wiki/Microwave_digestion

    Microwave digestion is a chemical technique used to decompose sample material into a solution suitable for quantitative elemental analysis. [1] It is commonly used to prepare samples for analysis using inductively coupled plasma mass spectrometry (ICP-MS) , atomic absorption spectroscopy , and atomic emission spectroscopy (including ICP-AES ).

  7. Non-thermal microwave effect - Wikipedia

    en.wikipedia.org/wiki/Non-thermal_microwave_effect

    Non-thermal microwave effects or specific microwave effects have been posited in order to explain unusual observations in microwave chemistry.The main effect of the absorption of microwaves by dielectric materials is a brief displacement in the permanent dipoles which causes rotational entropy.

  8. Dielectric heating - Wikipedia

    en.wikipedia.org/wiki/Dielectric_heating

    A microwave oven uses dielectric heating to cook food.. Dielectric heating, also known as electronic heating, radio frequency heating, and high-frequency heating, is the process in which a radio frequency (RF) alternating electric field, or radio wave or microwave electromagnetic radiation heats a dielectric material.
