Here we show that overcoordinated hydrogen bond environments can be identified in both the ambient and supercooled regimes of liquid water by combining experimental Raman multivariate curve resolution measurements and machine learning accelerated quantum simulations. In particular, we find that OH groups appearing in spectral r","authors_text":"Andres S. Urbina, Dor Ben-Amotz, Patrick K. Wise, Thomas E.
