- Title
- Infrared spectra and optical constants of astronomical ices: I. Amorphous and crystalline acetylene
- Abstract
- Here we report recent measurements on acetylene (C$_2$H$_2$) ices at temperatures applicable to the outer Solar System and the interstellar medium. New near- and mid-infrared data, including optical constants (n, k), absorption coefficients (\ensuremathα), and absolute band strengths (A), are presented for both amorphous and crystalline phases of C$_2$H$_2$ that exist below 70 K. Comparisons are made to earlier work. Electronic versions of the data are made available, as is a computer routine to use our reported n and k values to simulate the observed IR spectra. Suggestions are given for the use of the data and a comparison to a spectrum of Makemake is made.
