Calculation of transmission coefficients for some permeant molecules in human red cell and resting axolemma squid axon membranes

Quantum mechanical calculations of transmission coefficients for some permeant molecules across the human red cell and resting axolemma squid axon membranes are carried out. The calculations depend on (i) the molecular weight of the molecule and (ii) the depth and width of the potential well of the membrane. In most cases good agreement between calculated and experimental values is found.
