Because the laser induces a dipole moment within the molecule, both polar and nonpolar molecules can be studied. In our model we considered the following scattering mechanisms: scattering with acoustic phonons, ionized impurities, acoustic piezoelectric phonons, polar optical phonons, and optical nonpolar phonons. Identifying nonpolar transbilayer helices in amino acid sequences of membrane proteins. Contribution to the thermodynamics of protein folding from the reduction in water-accessible nonpolar surface area. In industry, it is used to color nonpolar substances like oils, fats, waxes, greases, various hydrocarbon products, and acrylic emulsions.

The molecule increasingly becomes overall more nonpolar and therefore less soluble in the polar water as the carbon chain becomes longer.

They are widely employed catalysts because they are soluble in the nonpolar substrates, such as the alkyd resins or linseed oil.

It is also needed to render nonpolar compounds polar so that they are not reabsorbed in renal tubules and are excreted.

The dyes used have to be soluble in the fuels they are added to and therefore in hydrocarbon-based nonpolar solvents (solvent dyes).

In nonpolar solvents, a range between 0.2 and 0.6 kcal/mol has been estimated, but in polar solvents the axial conformer may be more stable.

Nonpolar materials such as hydrocarbons traditionally have relatively low surface energies, however this property alone is not sufficient to achieve superhydrophobicity.
