The SI unit of molar absorption coefficient is the square metre per mole (m 2 /mol), but in practice, quantities are usually expressed in terms of M −1 ⋅cm −1 or L⋅mol −1 ⋅cm −1 (the latter two units are both equal to 0.1 m 2 /mol).
Extinction coefficient refers to several different measures of the absorption of light in a medium: Attenuation coefficient , sometimes called "extinction coefficient" in meteorology or climatology Mass extinction coefficient , how strongly a substance absorbs light at a given wavelength, per mass density

Absorption spectrum of methylene blue, in terms of the molar extinction coefficient (base 10 logarithm). In this dataset a peak absorbance of 1.7 (i.e. 98% of transmitted light absorbed) was observed with 665 nm light passing through 1 cm of 10 micromolar methylene blue solution. The maximum absorption of light is near 670 nm.

The first molar ionization energy applies to the neutral atoms. The second, third, etc., molar ionization energy applies to the further removal of an electron from a singly, doubly, etc., charged ion. For ionization energies measured in the unit eV, see Ionization energies of the elements (data page). All data from rutherfordium onwards is ...

Monster-taming games share core mechanics such as being able to capture creatures, train them, and use them in battle against similar creatures. [1] In many such games, these creatures are the only means of combat, although the darker-themed Megami Tensei series also allows the player to participate in combat, using weapons such as guns.
