Capacitance measurements have been employed to study the influence of an in-plane magnetic field on two-dimensional electron systems in semiconductor heterostructures. For electrons confined in quantum wells we have found that the magnetic field-induced shifts of the capacitance depend upon the symmetry of the confining potential. In conventional single heterojunction devices the magneto-capacitance is observed to depend strongly upon the sheet density of the two-dimensional electron system and exhibits a curious minimum at intermediate magnetic fields.
