- Raman is a light scattering technique, whereby a molecule scatters incident light from a high intensity laser light source. Most of the scattered light is at the same wavelength (or colour) as the laser source and does not provide useful information – this is called Rayleigh Scatter.aman Spectroscopy is a non-destructive chemical analysis technique which provides detailed information about chemical structure, phase and polymorphy, crystallinity and molecular interactions.

- Intensity is the quality of being intense. In physics, it is the measurable amount of a property, such as force, brightness, or a magnetic field. In Earth science, the amount … of damage caused by an earthquake. it can also mean the amount of energy that a wave carries past a certain area each second.ound intensity or acoustic intensity I is defin … ed as the sound power Pac per unit area A. That is: I = Pac / A. The usual context is the noise measurement of sound intensity in the air at a listener's location.

Fuel loads and fire intensity Fire intensity table. Fire intensity, expressed in kilowatts per metre (kW/m), is the amount of energy released from each metre of headfire edge. One kW/m is equivalent to the energy released by a small bar radiator. Fire intensity depends upon how much fuel is burnt and how fast it burns.

- The Raman spectra (Raman scattering intensity as a function of the Stokes and anti-Stokes frequency shifts) is dependent on the rovibronic (rotational and vibrational energy levels of the ground electronic state) states of the sample.s with single molecules, a given solid material has characteristic phonon modes that can help an experimenter identify it. In addition, Raman spectroscopy can be used to observe other low frequency excitations of the solid, such as plasmons, magnons, and superconducting gap excitations.

Radiofrequency Radiation (RF) Radiofrequency Radiation (RF) Radiofrequency (or RF) Radiation refers to electromagnetic fields with frequencies between 300 kHz and 300 MHz, while Microwave (or MW) Radiation covers fields from 300 MHz to 300 GHz. Since they have similar characteristics, RF and MW radiation are usually treated together.

- Resonance Raman (RR) spectroscopy is a name given to Raman spectroscopy when the incident laser frequency is close in energy to an electronic transition of a compound or crystal under examination.n resonance Raman spectroscopy, the energy of the incoming laser is adjusted such that it or the scattered light coincide with an electronic transition of the molecule or crystal. In most materials the incoming and outgoing electronic resonances are sufficiently broad that they can not be distinguished.

Translations for luminous intensity Luminous intensity. In photometry, luminous intensity is a measure of the wavelength-weighted power emitted by a light source in a particular direction per unit solid angle, based on the luminosity function, a standardized model of the sensitivity of the human eye. The SI unit of luminous intensity is the candela (cd), an SI base unit.

Resonance Frequencies at which the response amplitude is a relative maximum are known as the system's resonant frequencies, or resonance frequencies.At resonant frequencies, small periodic driving forces have the ability to produce large amplitude oscillations. This is because the system stores vibrational energy.he intensity is defined as the square of the amplitude of the oscillations. This is a Lorentzian function, and this response is found in many physical situations involving resonant systems. γ is a parameter dependent on the damping of the oscillator, and is known as the linewidth of the resonance.
