Literature absolute transition moments for A-X (0-0) bands have been used to obtain "best" values of Refor some 30 molecules. For isoelectronic sequences, Revs Z (heavy)/Z (light) is steeper at abscissae near 1.0 than a larger abscissae, contrary to expectation. For isovalent sequences, e.g. CH, SiH, Re(WY) is in each lower (average, 53%) than Re(WX). Suggestions will emerge for measurements which would be helpful in furthering diatomic molecular transition moment systematics. © 1975.
