N2 - We measure optical spectra of Nd-like W, Re, Os, Ir, and Pt ions of particular interest for studies of a possibly varying fine-structure constant. Exploiting characteristic energy scalings we identify the strongest lines, confirm the predicted 5(s)-4(f) level crossing, and benchmark advanced calculations. We infer two possible values for optical M2/E3 and E1 transitions in Ir17+ that have the highest predicted sensitivity to a variation of the fine-structure constant among stable atomic systems. Furthermore, we determine the energies of proposed frequency standards in Hf12+ and W14+.
