P700, or photosystem I primary donor, (where P stands for pigment) is the reaction-center chlorophyll ''a'' molecule in association with photosystem I. Its absorption spectrum peaks at 700 nm. [1]

9 relations: Absorption spectroscopy, Biological oxidizer, Chlorophyll, Energy level, Ferredoxin, P680, Photosynthetic reaction centre, Photosystem I, Photosystem II.

Absorption spectroscopy

Absorption spectroscopy refers to spectroscopic techniques that measure the absorption of radiation, as a function of frequency or wavelength, due to its interaction with a sample.
