It is shown that the equations describing chemical partitioning among Cl_x (HCl, Cl, ClO, ClNO₃), NO_t (NO, NO₂, NO₃, N₂O₅, HNO₂, ClNO₃) and HO_x (OH, HO₂) may admit multiple solutions. These solutions apply to the high latitude winter stratosphere where abrupt spatial variations may be expected for NO₂, ClO and ClNO₃.
