Standard refractive index measurements are taken at the "yellow doublet" sodium D line, with a wavelength (λ) of 589 nanometers. There are also weaker dependencies on temperature , pressure / stress , etc., as well on precise material compositions (presence of dopants , etc.); for many materials and typical conditions, however, these ...
Isoamyl acetate, also known as isopentyl acetate, is an ester formed from isoamyl alcohol and acetic acid, with the molecular formula C 7 H 14 O 2. It is a colorless liquid that is only slightly soluble in water, but very soluble in most organic solvents. Isoamyl acetate has a strong odor which is described as similar to both banana and pear. [3]
Methyl butyrate, also known under the systematic name methyl butanoate, is the methyl ester of butyric acid.Like most esters, it has a fruity odor, in this case resembling apples or pineapples. [2]
n-Butyl acetate is an organic compound with the formula CH 3 CO 2 (CH 2) 3 CH 3. A colorless, flammable liquid, it is the ester derived from n- butanol and acetic acid . It is found in many types of fruit, where it imparts characteristic flavors and has a sweet smell of banana or apple.

3-Methyl-2-butanol (IUPAC name, commonly called sec-isoamyl alcohol) is an organic chemical compound. It is used as a solvent and an intermediate in the manufacture of other chemicals. [ 3 ]
The refractive index of materials varies with the wavelength (and frequency) of light. [27] This is called dispersion and causes prisms and rainbows to divide white light into its constituent spectral colors. [28] As the refractive index varies with wavelength, so will the refraction angle as light goes from one material to another.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
