Low-density amorphous water (H₂O) ice (Iₐl ice) deposited at 80 K onto a potassium bromide (KBr), zinc selenide (ZnSe) or cesium iodide (CsI) substrate, and held at 80 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 80 K and a pressure of ~1E-8 mbar, by infrared transmission spectroscopy from 1.1 to 22.1 µm.
