Wideband water spectrum, room temperature

In Fig. 2a we depict the wideband loss spectrum of water calculated in terms of the hat model for room temperature (27°C). For ice at —7°C a similar calculation (but in a much narrower band) is presented in Fig. 2b. The fitted molecular parameters are presented in Table I (some of these parameters will be determined below). During the lifetime Tor a dipole performs in water and ice about two librations and about six librations in supercooled water (mor = 5.6). 

Choosing room temperature as 20.2°C, we depict in Fig. 5a the wideband absorption frequency dependence a(v) of water H20 and in Fig. 6a we depict that of water D20. The fitted parameters of the model are presented in Table II. The total loss spectrum e"(v) is shown in Figs. 5b and 6b, respectively, for OW and HW. The solid lines in Figs. 5a,b and 6a,b mark the results of our calculations.
