Metastable cubic crystalline water (H₂O) ice (Ic ice) deposited at 150 K onto a aluminum oxide (Al₂O₃), potassium bromide (KBr) or cesium iodide (CsI) substrate, then cooled down to 120 K, and held at 120 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 120 K and a pressure of ~1E-8 mbar, by infrared transmission spectroscopy from 1.1 to 2.6 µm.

The transmission (T) spectrum is also provided in this dataset.

k spectrum should be considered a lower limit. The relative uncertainty in k is strongest in the transparent regions near 1.35 and 1.8 μm, while the relative uncertainty is very small where the absorptions are strong.

More information can be found in the publication and on the OCdb contributor's page.
