Peak positions and band strengths of the pure acetone ice bands studied in this work.
| Vibrational mode | Peak position (cm−1) |
A′ (b) | |
|---|---|---|---|
| 15 K (a) | 10 K (b) | (10−18 cm mol−1) | |
| CO in plane deformation | 532.7 | 533.6 | 2.13 |
| CCC asymmetric stretch | 1228.4 | 1228.9 | 7.35 |
| CH3 symmetric deformation | 1363.4 | 1364.4 | 13.9 |
| CH3 asymmetric deformation | 1417.9 | 1418.9 | 9.19 |
| C=O stretching | 1710.3 | 1711.4 | 26.7 |
Notes. The acetone band position and strengths for the amorphous ice at 10 K (Hudson et al. 2018) are shown for comparison.
