Direct Observation of the C + S₂ Channel in CS₂ Photodissociation

Abstract

Carbon disulfide (CS 2 ) is a typical triatomic molecule. Its photo-

Vibrationally excited molecular hydrogen production from the water photochemistry

“…For the photoexcitation energy being lower than 11.55 eV, the water molecule can further transfer to the B state through an avoid crossing between the D and B states 28 , and then return to the transition state around the D= Ẽ0 coupling. It is noted that this central atom elimination channel has also been observed previously in the photodissociation of OCS 42 , CO 2 43 , and CS 2 44 , where the dissociation mechanism has been illustrated as the molecular isomerization with one side atom moving to the other side via a nonadiabatic transition or a roaming process. In Table 2 The calculated energies and average bond lengths of vibrational states for H 2 (X 1 Σ g + ) and D 2 (X 1 Σ g + ).…”

Slice imaging study of NO2 photodissociation via the 12B2 and 22B2 states: the NO(X2Π) + O(3PJ) product channel

“…The experiment apparatus used in this study has been described in previous publications. [39][40][41][42] Briefly, the pulsed supersonic molecular beam was generated by expanding a mixture of 10% NO 2 and He into the source chamber via a pulsed valve (General valve, Parker Series 9), where it was skimmed before entering and propagating along the centre axis of the ion optics assembly (IOA, 23-plate ion optics) mounted in the reaction chamber. The molecular beam was intersected at right angles by the photolysis and probe laser beams between the second and third plates of the ion optics assembly.…”

Abiotic molecular oxygen production—Ionic pathway from sulfur dioxide

“…Similarly, recent studies suggest that most of the O 2 in Europa’s exosphere is produced by UV photolysis of H 2 O vapor ( 10 ). Also, Li and co-workers ( 11 ) most recently recorded a related pathway for the formation of S 2 + C after CS 2 VUV photodissociation. In 2016, Wang and co-workers ( 12 ) provided experimental evidence for a channel of dissociative electron attachment to CO 2 that produces O 2 + C − .…”
