One notable limitation pertains to what is commonly referred to as "naked hydrogens" within the force field. Specifically, this limitation arises from the absence of Lennard-Jones parameters for the hydrogen atoms of hydroxyl groups. Consequently, in the absence of explicit hydrogen parameters, the interactions involving chlorine and hydroxyl groups (Cl-OH) are approximated through the adjustment of a parameter known as . This parameter represents the atomic ratio of chlorine and oxygen in such an interaction, and is set to a fixed value of 0.37 nm for all interactions of this type in the CL&Pol force field.
