Crystalline orthorhombic acetylene (C₂H₂) ice deposited at 70 K onto a potassium bromide (KBr) substrate, and held at 70 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 70 K, by infrared transmission spectroscopy from 7000 to 3500 cm⁻¹ with a resolution of 2 cm⁻¹.

The transmission (T) spectrum of a 4.6-µm-thick sample is also provided in this dataset.
