H₂O Ice at 23 K

Ice Datasets
Description
Sample Type Ice
Components H₂O
Ratio 1
Substrate KBr
Phase / State Amorphous
Reference Temperature 23 K
Wavenumber (cm⁻¹) 650 - 4000
Wavelength (µm) 2.5 - 15.385

Amorphous water (H₂O) ice deposited at 23 K onto a potassium bromide (KBr) substrate, and held at 23 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 23 K, by infrared transmission spectroscopy from 4000 to 650 cm⁻¹ with a resolution of 3 cm⁻¹.

The accuracy of the n and k indices is estimated at ± 5%.
