The photoionization cross sections for the 4p shell of ions of the Kr isoelectronic sequence Rb+, Sr2+, and Y3+ are calculated. The configuration interaction theory and the perturbation theory are used to describe the many-electron effects. The relat

The photoabsorption spectrum of Kr-like Y3+ ions in the very soft x-ray/extreme ultraviolet spectral range where single (4s–np) and double (4p4p–nln'l') electron excitations dominate has been measured using a dual laser plasma photoabsorption tec

The 4p-subshell spectrum of Mo+ has been recorded, for the first time, in the wavelength range 500–200 A. The spectrum is dominated by a 4p → 4d 'giant resonance' on which extensive discrete structure is superposed. With only one exception the di

The T1←S0 absorption spectrum of 4H-pyran-4-thione (PT) was measured in a static cell at room temperature (550–620 nm) and in a seeded cold supersonic jet (580–600 nm) using the cavity ring-down (CRD) method. In the static cell absolute extinct

The very sensitive cavity ring-down method has been applied to the measurement of the absorption of 4-H-1-benzopyrane-4-thione (BPT) in a supersonic jet in the wavelength region of the S0→T1 and S0→S1 transition between 15800 and 16650 cm−1. Th

The solvent spectral shifts of the S0 f T1 origin bands of jet-cooled 4H-pyran-4-thione (PT) and 4H-1benzopyran-4-thione (BPT) were observed in phosphorescence excitation spectra. Van der Waals complexes (1:1) of seed molecules with the carrier gas w

The phosphorescence excitation spectrum of isolated 4-H-1-benzopyrane-4-thione molecules (BPT) in a pulsed supersonic jet was investigated by direct excitation of the first excited triplet state, S 0 → T 1 . The electronic origin at 15828 cm −1 i

The multiphoton (one-colour) excitation spectrum of jet-cooled 4-H-1-benzopyrane-4-thione (BPT) is investigated in the wavelength region from 570 to 640 nm. The emission from BPT after multiphoton excitation was detected in two wide ranges in the blu

The extinction spectra of static naphthalene and static biphenylene vapor, each buffered with a noble gas at room temperature, were measured as a function of time in the region between 390 and 850 nm after UV multi-photon laser photolysis at 308 nm.
