dn /dc a gateway parameter

dn /dc a gateway parameter. also known as Specific Refractive Index Increment sometimes given the symbol n (probably a bad idea) n = refractive index (unitless) c = polymer concentration (g/mL) dn /dc has units of mL/g. Why dn /dc matters. We use it to get molecular weight of polymers
