Spectra obtained in the experiment #12 of LIDA, from a mixture of H₂O: HCOOH (91:9), as seen with our AICE Interactive Toolkit. The curve in black is the spectrum at 15 K, and the rest of coloured curves correspond to spectra with increasing temperature, with a step of 15 K until 165 K (which is almost flat, as both species have desorbed). The spectra were originally published by Bisschop et al. (2007).
