“…These corrections yielded 69 400 cm" 1 (8.61 eV)s£lP, Pt I*s71 700 cm" 1 (8.89 eV). The third is the recent spectroscopic measurement by Blaise et al [3], who derived an ionization limit of 72 230±50 cm" 1 (8.955±0.006 eV) from the 5d()l s and 5d9%s levels, and the 5 d96f and 5d*6s5f levels, respectively. To arrive at this result, Blaise et al respectively assumed that the difference in the quantum defects of the Is and $$ electrons and the binding energies of the 5ƒ levels are the same as in Au I and Hg I.…”

Mass-selected, double-resonance, field-ionization spectroscopy is used to determine the first ionization po tential of the three abundant isotopes of platinum. By fitting up to 38 member of s and d Rydberg series of ionization potentials of l94Pt, ,wPt. and l%Pt are determined to be 72 2S6.6±0.9 cm-1 (8.958 6 8 ± 0.000 11 eV). This yields a revised value of 27 580+320 cm"1 (3.42±0.04 eV) for the bond strength of platinum

“…The parametric hfs analysis we carried out is based on a multiconfigurational fine structure calculation of Wyart [17], which takes into account the four odd configurations 5d96p, 5d86s6p, 5d76sZ6p and 5d97p, compare Fig. 1.…”

Abstract. The hyperfine structure of the odd configurations 5d96p and 5dS6s6p was studied with laser optogalvanic spectroscopy and high resolution interferometry in a platinum hollow cathode. A parametric hyperfine structure analysis for the configurations (5d + 6s)96p with 10 excited odd-parity levels was performed for 195pt. We ol 1160(320) obtained one-electron hfs parameters, asd = 10 35600(5300) MHz and a°~ = 1300 (780) Recently, we demonstrated good consistency in Pt [13] and also in another 5d-element, i.e. Re [14], between the configuration IS and the theoretical values for the electron density at the nucleus, 4rcl if(0)I z, proportional to the field shift. As an extention of our IS study, here, we performed a parametric hfs analysis in the odd Pt configurations (5d + 6s)96p, i.e. 5d96p, 5d86s6p, 5d76sZ6p.

“…An important part was played in this respect by the production of high-quality spectra of platinum by Sansonetti et al [2], as well as by the theoretical interpretation of these spectra and analysis of PtI energy levels by Blaise et al [3]. Sansonetti et al [2] investigated the spectrum on the short-wave side up to 113 nm, i.e., the spectrum includes a part of the VUV range.…”

Excitation of PtI Transitions Terminating on Singlet Levels

The method of extended crossing beams is used to investigate the excitation of platinum atom transitions terminating on singlet levels. Thirty eight excitation cross sections are measured at the electron energy of 30 eV; nine optical excitation functions are recorded in the electron energy range from zero to 200 eV. Also measured are eight excitation cross sections of transitions which have even upper levels. Possible excitation channels are discussed, which define the absolute values of cross sections and the form of optical excitation functions.
