Expressions are derived for the rotational energy levels of diatomic molecules in 4 Σ states. These expressions contain two rho-type doubling parameters (γ's), and thus differ from earlier expressions which contain only one such parameter. The new expressions are in better agreement with the experimental data, though some discrepancy still exists.
