Methanol (CH₃OH) ice deposited at 10 K onto cesium iodide (CsI) and polyethylene (PE) substrates, then warmed up to 120 K, and held at 120 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 120 K, by infrared transmission spectroscopy from 4000 to 50 cm⁻¹ with a resolution of 2 cm⁻¹.
The transmission (T) spectrum is also provided in this dataset.
