The real (n) and imaginary (k) parts of the complex index of refraction were determined using optical measurements done at a temperature of 20 K, by infrared transmission spectroscopy from 2500 to 1600 cm⁻¹ with a resolution of 1 cm⁻¹. The transmission (T) spectrum is also provided in this dataset. More information can be found in the publication and on the OCdb contributor's page."
