Ice Datasets
Description
Sample Type Ice
Components H₂O
Ratio 1
Substrate Au
Phase / State Dissociated
Reference Temperature 4.2 K
Wavenumber (cm⁻¹) 18311.665 - 18311.665

Dissociated water (H₂O) ice deposited at 4.2 K onto a gold (Au) substrate after passing through a microwave discharge, and held at 4.2 K during spectroscopic measurements.

The real part (n) of the complex index of refraction was determined using optical measurements done at a temperature of 4.2 K and a pressure < 5E-5 mm Hg, by ellipsometry at 5461 Å.

Error bars/uncertainties are provided in the downloadable data.
