Fig. 2. Analysis of temperature-dependent SFG spectra for P. syringae at a water surface.

Fig. 2

(A) Spectra for RT and 5°C along with two fitting components related to more weakly and strongly hydrogen-bonded water within the broad water spectrum. CH and nonresonant fitting components are not included here. (B) Plots of the amplitudes obtained from fits to the SFG spectra from RT to 5°C. The mode related to more strongly hydrogen-bonded water increases strongly, whereas the weakly hydrogen-bonded water mode remains almost unchanged.
