Evidence for lactone formation during infrared multiple photon dissociation spectroscopy of bromoalkanoate doped salt clusters

Abstract

Bromoalkanoates embedded in sodium iodide clusters undergo an intramolecular SN2 reaction to form lactone and bromide.

Spectroscopy and photochemistry of copper nitrate clusters

“…Ultraviolet/visible/near-infrared (UV/vis/NIR) photodissociation spectroscopy is a very powerful tool to characterize the complex electronic structure of transition metal complexes and clusters in the gas phase. [44][45][46][47][48][49][50][51][52][53][54] We recently investigated photochemical hydrogen evolution from hydrated magnesium, 55,56 the effect of salt environments on the reactions and photolysis of organic substances, [57][58][59] as well as the evolution of the hydration environment of a single electron 60 or a carbon dioxide radical anion 61 using action spectroscopy.…”

Magic cluster sizes of cationic and anionic sodium chloride clusters explained by statistical modeling of the complete phase space

“…[12][13][14][15][16] Gas-phase clusters are ideal models to study fundamental physical and chemical properties of pure and doped salts. [17][18][19] Mass spectrometric studies of alkali halide clusters date back to the 1970s, utilizing secondary ion mass spectrometry (SIMS) and gas aggregation followed by electron ionization (EI), as comprehensively reviewed by Martin. 20 Electrospray ionization has become the dominant way of preparing positively as well as negatively charged salt clusters.…”

Spectroscopy of cluster aerosol models: IR and UV spectra of hydrated glyoxylate with and without sea salt

“…We have recently studied a series of salt clusters containing organic molecules by both infrared spectroscopy [38][39][40][41][42][43] and UV/vis spectroscopy, [43][44][45] always in combination with high-level quantum chemistry. We were able to show that the photochemistry of glyoxylate in dry sea salt clusters differs from gaseous glyoxylate, resembling more closely the photochemistry of glyoxylic acid.…”
