Short description: database from the Astrochemistry laboratory (NASA GSFC) focused on low temperature Mid and Far-IR (2.5-100 µm) transmission spectra and optical constants of ices and small organic molecules and their mixtures

Access to data: IR Spectra - Optical Constants from IR Spectra

Sample types: Ices, nitriles, hydrocarbons, small organic molecules and some simple mixtures

Spectra types: transmission/absorbance spectra and optical constants over the Mid-IR (400-4000 cm-1) and Far-IR (100-500 cm-1))

Search tools: Web pages with static lists of ice names

Data format: ASCII (.txt), binary SPC/Brucker (.SPC)

Preview format: pdf (.pdf)

Metadata: limited: ice composition, sample thickness & growth rate, substrate, spectral resolution, formation and measurement temperature, reference…

Metadata format: in HTML page (.html) and part in header of data file (.txt)

Download: individual or series download

Notes: large number of ices, nitriles, hydrocarbons and complex organic molecules
