Even at normal incidence, the transmission spectra may be relatively sensitive. To demonstrate this. Fig. 7.13 shows the vOH band of water adsorbed on NaCl(lOO) at -27°C, which is lower than the freezing point of a saturated NaCl solution, and a pressure of 0.2 mbar (35% RH) [358]. The spectrum was recorded by the multiple-transmission technique. For this purpose, 11 crystals cleaved along the (100) faces of NaCl were collected in a pile with spacers of 0.1-mm Ta wire, so that the NaCl faces did not touch each other. To reduce reflection from the external air-NaCl boundary, wedged silicon windows were attached to both ends of the pile. Comparison of the band position of adsorbed water with that of water in various phases (the top of Fig. 7.13) suggests that at this temperature the adlayer is mostly in the liquid state. On this basis, the surface coverage can be evaluated by introducing the absorption index of bulk water in the modified BLB relationship ... 

Po is the saturated vapor pressure of the probe a is the area of the adsorbed molecule and is the dispersive component of the surface energy of the molecule in the liquid state Oo is the polarizability of the molecule, v is the proper frequency of the molecule Xt is the topology index of the molecule according to the method of Wiener modified by Barysz [179,180]...
