Here we explore the possibility of such an anomaly in infra-red and Raman spectroscopy of super-critical water (SCW) by varying the density across the Widom line just above its critical temperature. Vibrational phase relaxation is expected to be a sensitive probe of fluid dynamics. We carry out computer simulations of two different model potentials (SPC/E and TIP4P/2005) to obtain the necessary time correlation functions.
