Refractive index of 4 glycols versus wavelength and temperature
Listed in Teesside University Research Data Repository
The dataset consists of tables of refractive index values versus wavelength and temperature n(lambda, T) for 4 hygroscopic organic liquids.
Description
Each table corresponds to one liquid: (i) HEG – hexaethylene glycol, 96% abcr GmbH lot 1508060; (ii) PEG – pentaethylene glycol, 98.0%, Alfa Aesar lot 10207595 and pentaethylene glycol, 97.0%, abcr GmbH lot 1509179 (no differences in measurements were found) ; (iii) TPG – tripropylene glycol, ≥99%, Alfa Aesar lot H25W018; (iv) DPG – dipropylene glycol, mixture of isomers, 99%, Alfa Aesar lot 10201331.
The measurements cover the range from 390 to 1070 nm in wavelength and from 1 to 45ºC in temperature. Each data point corresponds to a mean value of several measurements. Outlier measurement series were discarded.

The accuracy of the refractive index measurement is estimated to be ±0.0003, while the accuracy of the wavelength measurement is ~1%, and the accuracy of the temperature measurement is ±0.5 K. The measurements were performed with a modified Abbe refractometer. The calibration was performed with water at each temperature from 5 to 45ºC and with ethylene glycol at 1ºC. The details of experimental setup and procedures can be found in [Jakubczyk et al., Chromatic dispersion and thermal coefficients of hygroscopic liquids: 5 glycols and glycerol, Scientific Data, (2023) 10:894, DOI: 10.1038/s41597-023-02819-3].
The SketchUp file (.skp, 2017 format) contains the corresponding 3D model, while the .mp4 file contains a walk-around video of the setup, generated from the model.
