FIG. 4.

Snapshots of chemically sensitive 2D time-lapse imaging of the early dynamics of a methanol–D₂O mixture. D₂O appears much darker due to the D–O stretching absorption near 2600 cm⁻¹ (3850 nm), while methanol remains nearly transparent. Bubbles are formed in the first 150 ms. Exposure time: 1 ms. https://doi.org/10.1063/5.0061661.6 Download video file ^{(17.6MB, mp4)} DOI: 10.1063/5.0061661.6; https://doi.org/10.1063/5.0061661.7 Download video file ^{(12.4MB, mp4)} DOI: 10.1063/5.0061661.7; https://doi.org/10.1063/5.0061661.8 Download video file ^{(13.1MB, mp4)} DOI: 10.1063/5.0061661.8
