Electromagnetic transitions in {sup 22}F were investigated using the {sup 9}Be({sup 14}C, p) reaction at E{sub lab}=22 MeV. Proton-{gamma} and proton-{gamma}-{gamma} coincidences were measured using a segmented E-{delta}E Si telescope and the Florida State University {gamma} detector array. {gamma}-ray energies, intensities, and branching ratios were measured, and mean lifetimes were inferred using the Doppler-shift attenuation method. Several new states and many new {gamma}-decay branches were observed. The results are compared with sd shell model calculations using the USD, USDA, and USDB interactions. The excitation energies of the states below 2 MeV agree slightly better with the calculations using the USD interaction, while the levels between 2 and 4 MeV agree somewhat better with those using the newer USDA and USDB interactions.
