Abstract
The refractive index of NH4Cl-H2O solutions has been measured over a w avelength range from 496.5 to 690 nm. The NH4Cl concentration was vari ed from 15 to 30 wt. % over a temperature range from 10 to 35 degrees C. We obtained mathematical equations relating the refractive index to wavelength, temperature, and concentration using the least-squares me thod. A knowledge of these properties is important for analyzing and m odeling the dendritic growth of this system. (C) 1996 Optical Society of America
