Deuterated vibrational modes of CD3OH in astrophysical ice mixtures at 10 K in the mid-infrared region.
| Mode/cm−1 (µm) | Binary mixture | H2O matrix | CO matrix |
|---|---|---|---|
| CD3 sym. stretch | 2072 (4.82) | 2075 (4.82) | 2074 (4.82) |
| CD3 asym. bend | 1068 (9.36) | 1069 (9.35) | 1070 (9.35) |
| C − O stretch | 982 (10.18) | 981 (10.19) | 983 (10.17) |
| CD3 rock | 899 (11.12) | 903 (11.07) | 899 (11.12) |
Notes. Band positions are given in cm−1, with corresponding wavelengths in μm shown in parentheses. Minor shifts of 1–3 cm−1indicate preservation of deuterated features across different ice matrices.
