The energy of the first excited state in the neutron-rich N=28 nucleus {sup 45}Cl has been established via in-beam {gamma}-ray spectroscopy following proton removal. This energy value completes the systematics of the E(1/2{sub 1}{sup +})-E(3/2{sub 1}{sup +}) level spacing in odd-mass K, Cl, and P isotopes for N=20-28. The results are discussed in the framework of shell-model calculations in the sd-fp model space. The contribution of the central, spin-orbit, and tensor components is discussed from a calculation based on a proton single-hole spectrum from G-matrix and {pi}+{rho} meson exchange potentials. A composite model for the proton 0d{sub 3/2}-1s{sub 1/2} single-particle energy shift is presented.
