Water (H2O) ice deposited at 10 K onto cesium iodide (CsI) and polyethylene (PE) substrates, then warmed up to 140 K, and held at 140 K during spectroscopic measurements.
The real (n) and imaginary (k) parts of the complex index of refraction were determined using optical measurements done at a temperature of 140 K, by infrared transmission spectroscopy from 4000 to 50 cm⁻¹ with a resolution of 8 cm⁻¹ in the mid-infrared (4000-500 cm⁻¹) and 4 cm⁻¹ in the far-infrared (500-50 cm⁻¹).
