A complete experimental analysis on the use of Ge–B co-doped fiber Bragg grating sensor for a concentration and refractive index measurement is presented. Thus, it is the main aim of this work to develop a model for predicting the refractive index of binary ionic liquid system containing alcohol (methanol or ethanol or 1-propanol). In optics, the refractive index (also known as refraction index or index of refraction) of a material is a dimensionless number that describes how fast light travels through the material. Refractive index of ethanol solutions, This site is in construction. C4H8O2 (Ethyl acetate, EtOAc, EA) C2H6OS (Dimethyl sulfoxide, DMSO) It is a light, volatile, colourless, flammable liquid with a distinctive alcoholic odour similar to that of ethanol. Artificial neural network (ANN) algorithm with two hidden layers. Refractive index data from ThermoIL Database were used. Methanol, also known as methyl alcohol amongst other names, is a chemical with the formula C H 3 O H (a methyl group linked to a hydroxyl group, often abbreviated MeOH).
