Abstract
Photofragmentation/ionization of dimethyl sulphide (DMS) and dimethyl disulphide (DMDS) clusters, i.e., (CH3SCH3) n and CH3SSCH3) n , subjected to nanosecond laser pulses of 355 and 532 nm of intensity ~5 × 109 W/cm2, has been studied using time-of-flight mass spectrometry. At 355 nm, these clusters were found to exhibit multiphoton dissociation/ionization behavior similar to that reported earlier for their corresponding monomer. In contrast at 532 nm, these clusters were found to exhibit Coulomb explosion phenomenon resulting in generation of multiply charged atomic ions of carbon (up to C4+) and sulphur (S6+), along with other fragment ions arising from multiphoton dissociation/ionization of DMS and DMDS clusters.
