Deuterated vibrational modes of CH2DOH in astrophysical ice mixtures at 10 K in the mid-infrared region.
| Mode/cm−1 (µm) | Binary mixture | H2O matrix | CO matrix |
|---|---|---|---|
| C − D stretch | 2179 (4.59) | 2183 (4.58) | 2181 (4.59) |
| CH2 wag | 1326 (7.54) | 1329 (7.52) | 1325 (7.55) |
| CH2 twist | 1293 (7.73) | 1294 (7.73) | 1293 (7.73) |
| OCD bend | 919 (10.88) | 917 (10.90) | 920 (10.87) |
Notes. Band positions are given in cm−1, with corresponding wavelengths in μm shown in parentheses. Minor shifts of 1–4 cm−1 indicate preservation of deuterated features across different ice matrices.
