Abstract: The combined fine and hyperfine structure of the 23P states in 3He is calculated within the framework of nonrelativistic quantum electrodynamics. The calculation accounts for the effects of order mα6 and increases the accuracy of theoretical predictions by an order of magnitude. The results obtained are in good agreement with recent spectroscopic measurements in 3He.
