specific absorbance-
it is absorbance in a solution containing one gm of substance in 100 ml solvent in 1cm shell.
so it is having a difference with absorbance which is negative logarithm of incident light to the transmitted light.

UV Visible spectroscopy measures the response of a sample to ultraviolet and visible range of electromagnetic radiations. Molecules and atoms have electronic transitions while most of the solids have interband transitions in the UV and Visible range. Most molecules have a pi to pi* transition, involving pi electrons. The most important kind of UV/Vis Spectr. is Dispersion based spectroscopy. It involves a disperive medium like prism or grating to separate the different wavelengths.

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.
me too searching!!
* 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.
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.
A spectrometer shoots light through a sample and detects absorbance while a fluorimeter detects the intensity of fluorescence of a given sample.
The acronyms are synonyms. AES = Atomic Emission Spectroscopy OES = Optical Emission spectroscopy

Transmittance is the ratio of light energy that is falling on a body. Absorbance is how much light energy is actually going into the body.
Turbidity measures the degree of light is scattered by suspended particulate material and soluble colored compounds in the water. Absorbance measures the amount of light absorbed by the constituents in the water with a specified wavelength.
in primary light absorbed by outer molecule while in secondary re-absorbance occurs
