Explanations | |||||
Occupiable volume | That portion of the available volume within the cell that can be visited by the center of a (spherical) water molecule (radius = 1.4Å). The available volume is the unit cell volume remaining after the van der Waals atomic sphere volumes are subtracted. | ||||
Occupiable area | The area of that surface visited by the center of the water molecule. | ||||
Accessible volume | That portion of the occupiable volume that has continuity between all unit unit cells. Some pores/cavities have windows that are too small to allow the water molecule access, and so represent isolated occupiable regions. | ||||
Accessible area | The area of that surface visited by the center of the water molecule. | ||||
Specific occupiable area | Occupiable area per unit volume | ||||
Specific accessible area | Accessible area per unit volume |
