Nmr diffusion coefficient study of steroid cyclodextrin inclusion complexes

where A is the area (m 2 ), N is the number of molecules, t is the time (s), P is water vapor pressure (Pa) (molecules going onto the surface), or the difference in the vapor pressure of the material and the actual vapor pressure present (molecules leaving the surface), M is the molar mass of water (kg mol -1 ), R is the gas constant (J mol -1 K -1 ) and T is the temperature (K). For evaporation/sublimation the key factor is the saturation vapor pressure which controls the maximum rate possible (α = 1); ~2 fm day -1 at 100 K, P = ~10 fPa; ~2 pm hr -1 at 120 K, P = ~ nPa; ~1 mm s -1 at 0 °C, P = ~600 Pa.
