Atomic absorption spectroscopy (AAS) An analytical technique in which a sample is vapourised and the nonexcited atoms absorb electromagnetic radiation at characteristic wavelengths.
Atomic spectroscopy is an expensive analytical method which uses absorption (AAS), emission (AES) and fluorescent (AFS) characteristics of the analyte.
Infrared (IR) spectroscopy is a technique used for determining the structure (and sometimes concentration) of molecules by observing how infrared radiation is absorbed by a sample.
Red-hot gases give line spectrum, i.e. is they emit electromagnetic rays of defined wavelengths. That kind of emission line of spectrum is characteristic of each chemical element.
Wavelengths of electromagnetic waves can be shown with the help of electromagnetic radiation spectrum. Electromagnetic radiation spectrum is divided into several areas from γ-radiation of very short wavelengths and great energy to radio waves with wavelengths up to 1 000 m. The human eye can only see a narrow part of the electromagnetic spectrum - visible radiation.
Reaction speed curve is a graphic presentation of the reactant quantity change in dependence on time value.
Specific heat is the quantity of heat required to raise the temperature of one gram of a substance by one degree Celsius.
Specific quantity is often convenient to express an extensive quantity (e.g., volume, enthalpy, heat capacity, etc.) as the actual value divided by mass. The resulting quantity is called specific volume, specific enthalpy, etc.
Spectrophotometry is a determination of the concentration of a material in a sample by measurement of the amount of light the sample absorbs.
