C₂H₂ Ice at 12 K


Ice Datasets
Description
Sample Type Ice
Components C₂H₂
Ratio 1
Substrate KBr
Phase / State Amorphous
Reference Temperature 12 K
Wavenumber (cm⁻¹) 500 - 5000
Wavelength (µm) 2 - 20

Amorphous acetylene (C₂H₂) ice deposited at 12 K onto a potassium bromide (KBr) substrate, and held at 12 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 12 K, by infrared transmission spectroscopy from 5000 to 500 cm⁻¹ with a resolution of 2 cm⁻¹.

The transmission (T) spectrum of a 0.5-µm-thick sample is also provided in this dataset.
