Metastable low-temperature crystalline ethane (C₂H₆) ice deposited at 45 K onto a potassium bromide (KBr) substrate, then cooled down to 11 K, and held at 11 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 11 K, by infrared transmission spectroscopy from 4500 to 500 cm⁻¹ with a resolution of 1 cm⁻¹.
The transmission (T) spectrum of a 0.48-µm-thick sample is also provided in this dataset.
More information can be found in the publication and on the OCdb contributor's page.
