README

Supplementary Material 1: Additional information on uncertainties, and the effects of diffraction grating and spectral resolution, vapor bubble volume and density, and integration times and accumulations.
 
Supplementary Material 2: Spectral data for 24 C and 37 C, provided as .txt files and skewness images (.png).

Supplementary Material 3: Video files of two experiments: a cooling experiment shown in Figure 2 of the main text, and another of a bubble at 𝑇amb under microscope light where the vapor bubble can be seen bouncing in the liquid.

Supplementary Material 4: Jupyter notebook (.ipynb) allowing users to calculate peak asymmetry.

Supplementary Material 5: Tables of raw experimental data.

Supplementary Material 6: Schematic of Peltier heating stage setup.
