“…In the nonlinear least squares fit, presented in Figure 2, I and δ were obtained simultaneously, yielding a value of 62317 (6) cm -1 for I and 1.02(9) for δ. Both of these I and δ values are in very good agreement with the more-precise values of 62317.3(2) and 1.018(2) from Loock et al, 7 and the even more precise values of I available, 62317.44(10) 3 and 62317.46(3). 15 We note that a similar analysis by…”

Resonance-enhanced multiphoton ionization (REMPI) spectra of laser-ablated copper atoms entrained in a supersonic free jet expansion are reported. Depending on the ionization scheme employed, and the conditions under which the copper atoms are produced, very different spectra are produced, and these are discussed. In some circumstances, high proportions of metastable atoms survive the ablation and expansion process and are clearly seen in the spectra. The spectroscopic transitions for the observed lines are identified, and it is noted that some caution is merited in the assumption that only ground state copper atoms are present following laser ablation.

“…Thus, both 2 D 5/2 and 2 D 3/2 states should be accessible. However, the spin-orbit splitting at high n number gets smaller 7,15 and is of the order of our laser linewidth or less, and so we are unable to resolve the two components in the present work.…”

“…Maziarz et al [11] related these phenomena to the ionization energy difference between Ag and PAHs. When the Ag ionization energy (7.57 eV) [26,27] is greater than that of the PAH, the radical PAH +• is observed. This was the case in our experiments using pyrene (7.42 eV) [25] but such radical was not observed using fluoranthene (7.9 eV), in accordance with Ling and Lifshitz [28].…”

The objective of this work was to compare direct infusion in a Q-TOF mass spectrometer through three different atmospheric pressure sources, electrospray ionization (ESI), atmospheric pressure chemical ionization (APCI), and atmospheric pressure photoionization (APPI) coupled to a high resolution Q-TOF mass spectrometer. A complex mixture of PAH and oxy-PAHs, obtained after the air oxidation of fluoranthene on mineral substrates, was used to compare the different ionization abilities of these sources. Here, we propose analytical methods for the use of all sources. Final goal was to provide background to the choice of the most appropriate source in order to analyze complex organic mixtures as those encountered in polluted soils, water, sediments, as well as in petroleum.

“…During this study, a ion current of gold was observed in the presence of only the beam for the first step in the excitation scheme. Since the ionisation threshold of gold (74,409.0(2) cm −1 [10]) is slightly less than the sum Fig. 2 The two strongest AIS resonances observed of the energies of two photons at 267.673 nm, this ion current is attributed to the occurrence of two-step ionisation via a transition to the continuum from the first excited state by non-resonant absorption of second photon from the first step beam.…”

At the ISOLDE on-line isotope separation facility, the resonance ionisation laser ion source (RILIS) can be used to ionise reaction products as they effuse from the target. The RILIS process of laser step-wise resonance ionisation of atoms in a hot metal cavity provides a highly element selective stage in the preparation of the radioactive ion beam. As a result, the ISOLDE mass separators can provide beams of a chosen isotope with greatly reduced isobaric contamination. With the addition of a new three-step ionisation scheme for gold, the RILIS is now capable of ionising 26 of the elements. The optimal scheme was determined during an extensive study of the atomic energy levels and auto-ionising states of gold, carried out by means of in-source resonance ionisation spectroscopy. Details of the ionisation scheme and a summary of the spectroscopy study are presented.
