Femtosecond

Index Femtosecond

A femtosecond is the SI unit of time equal to 10−15 or 1/1,000,000,000,000,000 of a second; that is, one quadrillionth, or one millionth of one billionth, of a second. [1]

Ahmed Zewail

Ahmed Hassan Zewail (أحمد حسن زويل,; February 26, 1946 – August 2, 2016) was an Egyptian-American scientist, known as the "father of femtochemistry".

Chemical reaction

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.

Femtochemistry

Femtochemistry is the area of physical chemistry that studies chemical reactions on extremely short timescales (approximately 10−15 seconds or one femtosecond, hence the name) in order to study the very act of atoms within molecules (reactants) rearranging themselves to form new molecules (products).

Human eye

The human eye is an organ which reacts to light and pressure.

Infrared

Infrared radiation (IR) is electromagnetic radiation (EMR) with longer wavelengths than those of visible light, and is therefore generally invisible to the human eye (although IR at wavelengths up to 1050 nm from specially pulsed lasers can be seen by humans under certain conditions). It is sometimes called infrared light.
