WebFor high NO x SOA, as particles shrink, their refractive index returns to the value of the corresponding size particles before heating (limonene) or slightly higher (α-pinene). For low NO x however, the resulting refractive index is 0.05 ± 0.02 lower than the corresponding size undenuded particles. WebGeneral description.

It exists as a levogyre form in European turpentines, and as a dextrogyre form in turpentines found in North America. Sensitization mainly occurs in painters, polishers and varnishers, and in those in the perfume and ceramics industry.
