The spectral lines λ226.5, λ441.6, λ806.7 and λ853.3 nm of Cd II and λ508.6 nm of Cd I have been studied under high resolution by means of digital recording interferometry. The relative positions of all the stable isotopes of cadmium in all the lines have been deduced from the measurements. The main object of this study was to provide precise data for the simple p–s transitions λ226.5, λ806.7 and λ853.3 nm. Such lines are the most favourable for theoretical interpretation, and the new results are intended to provide a basis for the separation of mass and field effects in measured isotope shifts in cadmium. The hyperfine structure intervals, which are important in the interpretation of isotope shifts, have also been measured for all the levels involved in the five transitions.

The lines λ 444.2nm, λ 304.2nm and λ 306.5nm of the arc spectrum of platinum have been studied under high resolution by using digital recording interferometry. The work extends the range of nuclei for which isotope shifts have been measured to include 190 Pt, and has provided some improvement in accuracy for the shifts involving other isotopes. Data are now available for all the stable platinum nuclei; the relative shifts, which are closely proportional to the changes in mean square radius of the proton distribution, are as follows: 190, 192; 0.905 ± 0.028.192, 194; 0.969 ± 0.007. 194, 195; 0.456 ± 0.004. 194, 196; 1.0. 196, 198; 1.084 ± 0.004. The data are discussed in terms of recent measurements of nuclear deformation in platinum. The hyperfine splittings of some levels have also been deduced from the optical measurements.
