Low-density amorphous water (H2O) ice (Ial ice) deposited at 50 K onto a potassium bromide (KBr), zinc selenide (ZnSe) or cesium iodide (CsI) substrate, and held at 50 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 50 K and a pressure of ~1E-8 mbar, by infrared transmission spectroscopy from 1.1 to 22.1 µm.
