What is Specific Refractivity?

Specific refractivity is a parameter that characterizes the electronic polarizability of a unit mass of a substance in the high-frequency electromagnetic field of a light wave. It is equal to the substance’s molecular refraction divided by its molecular weight.

Here are some questions and answers about specific refractivity:

• What is specific refractivity?
• How is specific refractivity calculated?
• What are the applications of specific refractivity?

Here is the formula for calculating specific refractivity:

r = R / M

where:

• r is the specific refractivity of the substance
• R is the molecular refraction of the substance
• M is the molecular weight of the substance

Specific refractivity can be used to determine the molecular weight of a substance, as well as its polarizability. It can also be used to study the structure and properties of molecules.
