A. R. Forouhi and I. Bloomer deduced dispersion equations for the refractive index, n, and extinction coefficient, k, which were published in 1986 [1] and 1988. [2] The 1986 publication relates to amorphous materials, while the 1988 publication relates to crystalline.
The shortest wavelength's index is , and the longest's is . Abbe numbers are used to classify glass and other optical materials in terms of their chromaticity . For example, the higher dispersion flint glasses have relatively small Abbe numbers V < 55 {\displaystyle V<55} whereas the lower dispersion crown glasses have larger Abbe numbers.
2-Chloro-6-fluorobenzaldehyde is prepared by oxidation of 2-chloro-6-fluorotolulene by chromyl chloride. [3] It reacts with sodium hydroxide to give a mixture of 2-chloro-6-fluorobenzene and 6-chlorosalicaldehyde. [4] 2-Chloro-6-fluorobenzaldehyde is used in the production of the antiseptics dicloxacillin and flucloxacillin.
The dispersity (also known as the polydispersity index) of a sample is defined as M w divided by M n and gives an indication just how narrow a distribution is. [ 2 ] [ 3 ] The most common technique for measuring molecular mass used in modern times is a variant of high-pressure liquid chromatography (HPLC) known by the interchangeable terms of ...
Fluorobenzene is an aryl fluoride and the simplest of the fluorobenzenes, with the formula C 6 H 5 F, often abbreviated PhF. A colorless liquid, it is a precursor to many fluorophenyl compounds. A colorless liquid, it is a precursor to many fluorophenyl compounds.
