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). In a 1988 issue of the journal Science, Ahmed Hassan Zewail published an article using this term for the first time, stating "Real-time femtochemistry, that is, chemistry on the femtosecond timescale.

Attosecond

An attosecond (abbreviated as as) is a unit of time in the International System of Units (SI) equal to 10−18 or 1⁄1 000 000 000 000 000 000 (one quintillion) of a second.

Chemical reaction

Chemical reactions are the processes that result in the transformation of one or more chemical substances into different substances.

Femtosecond

A femtosecond is a unit of time in the International System of Units (SI) 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.
