...If the refractive index of a gas is n , its density is ρ, the molecular weight of the gas is M , its polarizability is α, Avogadro's number is N A , and the dielectric constant of a vacuum is ε 0 , then it can be expressed as follows. This relationship was independently derived by HA Lorentz of the Netherlands and Ludwig Valentin Lorenz of Denmark (1829-91), and it shows that the refractive index of a gas, n , can essentially be calculated if the polarizability, α, of the gas molecule is given. The quantity on the right hand side is written as R 0 and is called the molar refraction. ... *Some of the terminology that mentions "Lorenz, LV" is listed below.

…気体の屈折率をn,密度をρとし,その気体の分子の分子量をM,分極率をα,アボガドロ数をNA,真空の誘電率をε0とすると,で表される。この関係式は,オランダのH.A.ローレンツとデンマークのL.V.ローレンツLudwig Valentin Lorenz(1829‐91)によってそれぞれ独立に導き出されたもので,気体の屈折率nは,本質的にその気体の分子の分極率αが与えられれば求められることを示している。右辺の量はR0と書かれ,モル屈折と呼ばれる。… ※「Lorenz,L.V.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
