Usage

General Description

(3H)sulfanyl, also known as tritiated hydrogen sulfide, is a radioactive form of hydrogen sulfide that is commonly used in scientific research and industrial applications. It is produced by replacing one or more of the hydrogen atoms in hydrogen sulfide with tritium, a radioactive isotope of hydrogen. (3H)sulfanyl is primarily used as a tracer in studies of sulfur metabolism, as well as in the synthesis of radiolabeled compounds for use in radiopharmaceuticals. Due to its radioactive nature, (3H)sulfanyl must be handled with care and disposed of properly to mitigate potential health and environmental risks associated with its use.

Ultraviolet photodissociation dynamics of H2S and D2S

Nascent SH(X 2Πi, v''= 0,1) and SD(X 2Πi, v''= 0,1) rotational state population distributions, spin-orbit state population ratios, and Λ-doublet state population ratios have been measured following the UV excimer laser photodissociation of H2S (λ = 193, 222, and 248 nm) and D2S (λ = 193 and 222 nm), respectively.Nascent SH(X 2Πi, v'' = 0) rotational state distributions following 193 nm photodissociation of cold H2S in a free jet expansion vs 300 K H2S in a flowing gas cell were essentially the same, indicating that photofragment angular momentum must be originating predominantly in the dissociation event, and not from rotational energy contained in the parent triatom.Laser excitation spectra of SH(X 2Πi, v''= 1) and SD(X 2Πi, v''= 1) have been recorded for the first time.Rotational state distributions for SH(X 2Πi, v'') and SD(X 2Πi,v'') are independent of v''. Λ-doublet population ratios of the nascent photofragments are essentially unity for all the cases measured.The nascent rotational state distributions are consistent with an impact parameter model for the dissociating triatomic molecule.

Two-photon resonance enhanced MPI-PES above the lowest ionization threshold. Observation of the [a(1)Δ)]5pπ(2)Φ state of the SH (SD) radical

A (2+1) resonance enhanced multiphoton ionization photoelectron spectroscopy (REMPI-PES) study of the hitherto unobserved [a(1)Δ]5pπ(2)Φ Rydberg state of the SH (SD) radical is reported. Despite the fact that this state has an excitation energy which exceeds the lowest ionization energy, ionization is observed to occur preferentially by the absorption of a third photon after the two-photon excitation step, rather than through autoionization. Photoelectron spectra show a large asymmetryin the rotational branching ratios, which is attributed to the high value of Λ(+) in the ionic state.

Predissociation dynamics of the A 2Σ+ state of SH and SD

The technique of cavity ring-down spectroscopy has been used to investigate predissociation in the A 2Σ+ state of the SH and SD radicals. Spectra were recorded of the A-X (1,0) band of SH and the (1,0), (2,0) bands of SD. Linewidth measurements of transitions to individual rovibrational levels of the A state revealed increasing predissociation rates with vibrational and rotational quantum number. These and all other available data have been reproduced, quantitatively, by Fermi Golden Rule calculations employing the best (experimentally determined) analytic potential for the A state and ab initio repulsive potentials and spin-orbit coupling matrix elements.
