This list essentially updates a classical list published by M.B. Huglin over a quarter of a century ago (Huglin, M.B., Light Scattering from Polymer Solutions, Academic Press, London, Chapter 6, 1972). The proliferation of light scattering instrumentation (including multi-angle laser photometers coupled on-line to size exclusion chromatography columns, field-flow-fractionation and viscosity equipment) and a re-surgence of interest in analytical ultracentrifugation using refractive index based optical detection systems means there is a wide a user base as ever.
Unfortunately it is not possible to calculate dn/dc values on the basis of molecular composition (unlike density increments or partial specific volumes so widely used in analytical ultracentrifugation). Of course a light scattering or ultracentrifuge user can make his own measurements using appropriate instrumentation for which there are high-precision refractometers now available (in particular the Optilab DSP, Wyatt Technology Corp., Santa Barbara, USA). However, the accuracy with which these measurements can be made is not necessarily dependent on refractive index measurement but on concentration measurement, a parameter for which despite painstaking care, an accuracy better than 1% is rare. It is therefore useful to the scientist if he/she has access to earlier data recorded by some other user.
dn/dc values are not only highly dependent on the solvent, but also on temperature and they can show a dispersion with the wavelength, l, of the incident light used for the measurement. Care has been taken to specify those parameters if available from the original reference, so that the reader can choose a value most appropriate for his/her application.
