    • Strictly speaking, it is not physically correct to model the heating signal via a heated ground state. The reason is that this approach implicitly attributes the absorption change due to heating to only the relaxed HDO molecules. In reality, however, the temperature increase is experienced by all HDO molecules (irrespective of whether they had been excited or not, so that they all contribute to the heating signal. A more physical way of modelling the heating is to incorporate the absorption change due to the increased temperature into a time-dependent σ01(ω. t, However, it was previously shown that this approach leads to a heating term that is identical to the one in equation 5 except for a correction factor (1, Fe-kIt) where F is the fraction of excited HDO molecules.17 Because this fraction does not exceed a few percent, it can be safely ignored
