Two-photon state selection and angular momentum polarization probed by velocity map imaging: Application to H atom photofragment angular distributions from the photodissociation of two-photon state selected HCl and HBr

“…14 The larger spin-orbit interaction in HBr compared to HCl results in a departure from a Hund's case ͑a͒ description with the result that, for the perpendicular two-photon pathway, both the 1 ⌸ 1 and 3 ⌸ 1 states are able to contribute. [43][44][45] More importantly, for the parallel pathway, the 3 ⌸ 0 (⍀ϭ0) intermediate state gains strength through spin-orbit mixing with the ground state. In the single-photon A-band absorption spectrum of HBr centered around 243 nm one can hence find a considerable parallel component.…”

O(3Pj) atom formation from photodissociation of ozone in the visible and ultraviolet region

“…that are produced from the photodissociation of O2 (12)(13)(14)HCl (21). C12 (22), and chlorinated methanes (23) have been studied. The j-branching ratios in photodissociation processes should be determined by two factors: one is the adiabatic correlation between the dissociating molecular states and the atomic states.…”

Production of cold bromine atoms at zero mean velocity by photodissociation

“…With regard to the other halogens, cold chlorine atoms could be similarly produced by photodissociation of BrCl or Cl 2 and both molecules have highly anisotropic dissociation channels 34,35 , favouring efficient production of cold atoms. For Cl 2 the appropriate photodissociation wavelength to produce a Cl atom and a Cl * atom with velocities of 560 ms −1 (approximate beam speed when seeded in Ar) would be 480 nm, within the chlorine absorption band 36 . For F 2 the technique described here could not be used for producing cold atoms as the absorption crosssection is negligible near the dissociation threshold.…”
