Montesano 49, Napoli, Italy. Olive oil is a liquid fat obtained from the fruit of Olea europaea , a plant belonging to the Oleaceae family, which is widely cultivated and diffused in the Mediterranean area. It is largely produced and used since antiquity. It is mainly used and consumed as food but also as key ingredient in a wide variety of cosmetic products, e. In the last few decades, olive oil has received much attention as compared to the other seed-obtained oils as well as to the animal fats due to many functional compounds with positive effects on health. To maintain the genuine picture of olive oil, it is essential to assure its authenticity and quality. The presence of bioactive compounds, which characterize the olive oil owing to their antioxidant properties, can be assessed by spectroscopic and chromatographic methods.
Spectroscopy studies the interaction of radiated energy and matter. Different types of radiation can be used to study local structural environments of atoms in crystals, and therewith chemical and physical material properties. Various types of radiation differ in wavelength or frequency but are physically identical. When light interacts with a material, different processes can occur, reflection of light, transmission, scattering, absorption or fluorescence. All these processes take place when the incident radiation induces changes in energy levels, which can be of electronic, vibrational or nuclear nature.
Infrared spectroscopy IR spectroscopy or vibrational spectroscopy is the measurement of the interaction of infrared radiation with matter by absorption , emission , or reflection. It is used to study and identify chemical substances or functional groups in solid, liquid, or gaseous forms. The method or technique of infrared spectroscopy is conducted with an instrument called an infrared spectrometer or spectrophotometer which produces an infrared spectrum. An IR spectrum can be visualized in a graph of infrared light absorbance or transmittance on the vertical axis vs. A common laboratory instrument that uses this technique is a Fourier transform infrared FTIR spectrometer.
The UV spectroscopy ultraviolet spectroscopy is a physical technique of the optical spectroscopy that uses light in the visible VIS , ultraviolet and near infrared ranges. The measurement of a UV-VIS spectrum is recorded with a UV-VIS spectrometer , from which various devices from different manufacturers for general and specific applications are commercially available.
In physics and chemistry spectroscopy is an often used anlytical technique to identify chemical compounds through the spectrum emitted from or absorbed by them. Department of Chemistry.

Infrared spectroscopy IR spectroscopy is the spectroscopy that deals with the infrared region of the electromagnetic spectrum, that is light with a longer wavelength and lower frequency than visible light. It covers a range of techniques, mostly based on absorption spectroscopy. As with all spectroscopic techniques, it can be used to identify and study chemicals. A common laboratory instrument that uses this technique is a Fourier transform infrared FTIR spectrometer. The infrared portion of the electromagnetic spectrum is usually divided into three regions; the near-, mid- and far- infrared, named for their relation to the visible spectrum. The names and classifications of these subregions are conventions, and are only loosely based on the relative molecular or electromagnetic properties.

The UV-Vis spectroscopy is a technique that complements the structural elucidation of molecules.
- Вчера вечером я специально позвонил дежурному лаборатории систем безопасности и попросил его сегодня не выходить на работу. Сьюзан это не удивило. Она не могла припомнить, чтобы когда-то отменялось дежурство, но Стратмор, очевидно, не хотел присутствия непосвященных. Он и мысли не допускал о том, что кто-то из сотрудников лаборатории узнает о Цифровой крепости.
Не успел он набрать международный код, как в трубке раздался записанный на пленку голос: Todos los circuitos estan ocupados - Пожалуйста, положите трубку и перезвоните позднее. Беккер нахмурился и положил трубку на рычаг. Он совсем забыл: звонок за границу из Испании - все равно что игра в рулетку, все зависит от времени суток и удачи. Придется попробовать через несколько минут.
