Multiphoton dissociation/ionisation of dimethyl sulfide

Abstract: Multiphoton dissociation/ionisation studies have been carried out at 355 nm for dimethyl disulfide (CH 3 SSCH 3 ) using a time-of-flight-mass spectrometer. The ultraviolet (UV) absorption spectra of DMDS show two bands with maxima at 250 and 195 nm. 5,6 The first band has been attributed to the promotion of a nonbonding electron from sulfur to an antibonding orbital localised in the S-S bond (n S → s* SÀS transition). The second band at 195 nm has been assigned to n S → s* SÀS as well as n S → s* CÀS transitio… Show more

“…Details of the experimental setup have been described in our earlier publications1, 17–19 and only a brief account is given here. Neutral clusters of CS 2 were generated via supersonic expansion of room‐temperature CS 2 vapors seeded in helium/argon with different backup pressures varying from 1 to 5 bar.…”

“…This mechanism, according to previous results, relates the [CHS] + formation from the [CH 3 S] + fragment ion. Without the MND parametrization, this conclusion could not be inferred because the data are overlapped and there are not sufficient counts to define clearly an 'island'.…”
