Pure CH3CH2CN (1) Ice at 35 K

Description
Sample Type Ice
Components CH3CH2CN
Ratio 1
Substrate KRS-5 (for the mid-infrared region) and PE (for the far-infrared region)
Reference Temperature 35 K
Wavenumber (cm⁻¹) 75 - 789
Wavelength (µm) 12.674 - 133.333

Crystalline propionitrile (CH3CH2CN) ice deposited at a temperature between 50 and 100 K onto thallium bromoiodide (KRS-5) and polyethylene (PE) substrates, then annealed at 140 K and cooled down to 35 K, and held at 35 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 35 K and a pressure in the range of ~10⁻⁷ Torr, by infrared transmission spectroscopy from 789 to 75 cm⁻¹ with a resolution of 1 cm⁻¹ in the mid-infrared region and 4 cm⁻¹ in the far-infrared region.
