Photodissociation of (ICN)2 van der Waals dimer using velocity imaging technique

Abstract: Photodissociation of (ICN)(2) dimer from 265 to 270 nm are studied using time-of-flight mass spectrometry combined with velocity imaging technique. Both I(+) and I(2) (+) ions are found in the mass spectra. The I(2) (+) ions result from (1+1) resonant ionization of the neutral I(2) fragment that is produced in the photodissociation of dimer, but not from dissociative ionization of (ICN)(2); i.e., (ICN)(2) (+)+hnu-->I(2) (+)+2CN. The dissociation channels of I(2) (+) leading to I(+) are all found with parallel … Show more

“…For instance, photodissociation of hydrogen halides on/in various large rare gas clusters HX·Rg n (n ∼ 10 2 atoms) was studied on a versatile cluster beam apparatus in Göttingen. When cluster effects were observed in photofragment images, it has been usually attributed exclusively to dimers, e.g., (CH 3 I) 2 , 20 (HI) 2 , 21 (ICN) 2 , 22 and pyrrole-Xe. 18,19 The application of imaging techniques to cluster studies has been so far very limited and usually restricted to small species.…”

“…Imaging techniques are well suited to study the dissociation dynamics of various atomic and molecular clusters because the photofragment images enclose the complete information about the kinetic energy and angular distributions of the nascent photofragments. Until now the application of imaging techniques to cluster studies has been very limited and related mostly with photodissociation of dimers such as (CH 3 I) 2 [56,57], (ICN) 2 [58], (HI) 2 [59] and pyrrole-Xe [60]. Recently, the photodissociation of hydrogen bromide (HBr) in various large rare gas clusters HBr• • •Rg n with tens to hundreds rare gas atoms of either Argon (Ar) or Xenon (Xe) have been studied with VMI paving the way for more imaging studies in large cluster dissociation [61].…”
