Abstract
We recorded photoionization spectra of sulfur atoms in transitions from state 1 D in the range of 75 800-89 500 cm -1 . Dissociation of CS 2 after photolysis at 193 nm produced these sulfur atoms in a singlet excited state; they were then ionized with synchrotron radiation (NSRRC, beamline U9CGM) at resolution of up to 3cm -1 and detected with a quadruple mass filter. Rydberg series 3s 2 3p 3 ( 2 D 3/2 0 )nd[3/2] and 3s 2 3p 3 ( 2 D 5/2 0 ) ns[5/2] with n extending to 16 and 32, respectively, to limit 2 D 0 are assigned. New Rydberg series 3s 2 3p 3 ( 2 D 3/2 0 )nd [1/2] 1, ( 2 D 5/2 0 )nd[5/2], and ( 2 D 3/2 0 )nd[5/2] with n from 5-9 for the former two series and 7-13 for the latter are assigned. A new Rydberg line at 85 335 cm -1 is assigned to 3s 2 3p 3 ( 2 D 3/2 0 )6d 1 P. © 2008 American Institute of Physics.
