Photoinduced nucleation (PIN) experiments using CS2 and CS2/ethanol va
pors have been carried out in a flow photochemical reactor. Following
ultraviolet irradiation of the CS2-containing vapors, photoinduced nuc
leated particles were captured and characterized using mass spectromet
ry and Raman spectroscopy. Results of the analysis confirm the presenc
e of S-8 molecules in the particles produced by PIN of CS2 vapor. Addi
tional results consistent with these data but involving PIN of CS2 in
supersaturated I-propanol also from this laboratory are reviewed. The
role of sulfur in the PIN mechanism is discussed in the context of the
se particle characterization results and the gas-phase photochemistry
of CS2 and is shown to be consistent with an earlier description of CS
2 PIN from this laboratory.
