Description

Sample Type	Ice
Components	H₂O
Ratio	1
Substrate	Si
Phase / State	Polycrystalline hexagonal
Reference Temperature	186 K
Wavenumber (cm⁻¹)	3721.015 - 6981.188
Wavelength (µm)	0.002 - 2.687

Polycrystalline hexagonal water (H₂O) ice deposited at 186 K onto a silicon (Si) substrate, and held at 186 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 186 K, by infrared transmission spectroscopy from 6981 to 3721 cm⁻¹ with a resolution of 4 cm⁻¹.
