The g factors of the first excited 2{sup +} states in the {sup 112,114,116,122,124}Sn isotopes have been measured with high accuracy using the transient field technique in combination with Coulomb excitation in inverse kinematics. The experimental results are discussed in a qualitative way on the basis of empirical single-particle g factors of the relevant proton and neutron orbitals and are compared to a number of different theoretical calculations. The results are found to be best described by shell-model calculations in an extended configuration space. Clear evidence for the contribution of neutron pair excitations from the 1d{sub 3/2} to the 0h{sub 11/2} orbital to the wave function of the 2{sub 1}{sup +} state in {sup 122,124}Sn has been obtained.
