Abstract

High-resolution Fourier-transform spectra of a ²³²ThI₄–²³⁰ThI₄ electrodeless discharge lamp were obtained between 5600 and 36 000 cm⁻¹. These spectra were used to measure the splittings of more than 800 isotopic Th ii doublets to an accuracy of about 0.001 cm⁻¹. From these isotope shifts, 184 even- and 167 odd-level isotope shifts were determined. Level isotope shifts were determined for all known levels below 20 000 cm-, except for the even J = ½ level at 19 594 cm⁻¹. An empirical correlation of the level isotope shifts with a theoretical, configuration-mixing calculation was used to derive pure-configuration level isotope shifts.
