Empirical predictions are reported for the lifetimes of the 4{ital s}{sup 2}--4{ital s}4{ital p} resonance and intercombination transitions in the Zn isoelectronic sequence. The approach uses a direct-mapping reduction of available energy-level and lifetime data and imposes no theoretical assumptions or restrictions. Measured spectroscopic energy-level data are used to characterize intermediate coupling effects in terms of an effective singlet--triplet mixing angle, which is then used to convert lifetime data into mixing-reduced effective line strength factors. Through a linearizing screening parameterization, these reduced line strength factors are found to exhibit regularities that permit accurate interpolation, extrapolation, and smoothing and also provide a convenient exposition for sensitive comparison between experimental results and {ital ab} {ital initio} calculations.
