Positive ion desorption following electron impact dissociative ionization of ethane adsorbed on Ar, Kr, and Xe multilayers has been studied as a function of incident electron energy from threshold to 100 eV. Based on the dependence of ion yields on t

Low-energy (3-25 eV) electron interactions with multilayers of 2'-deoxyadenosine 5'-monophosphate (dAMP) were probed using X-ray photoelectron spectroscopy (XPS). Understanding how electrons damage the nucleotide dAMP, which is a building block of DN

Conversion of alkanes to functionalized compounds is a highly sought after goal. Under high reaction temperatures, desired intermediate products like alcohols, aldehydes, and carboxylic acids are more easily oxidized to CO2 than the starting alkane,

We demonstrate the efficient formation of carbon–nitrogen bonds starting from CH4 and NH3 on a metal surface at cryogenic temperatures. Electrons in the energy range of 1–90 eV are used to initiate chemical reactions in mixed molecular films of C

O(-) desorbed from amorphous and crystalline films of CO2 at 18 K under low energy electron impact is studied using time of flight mass spectrometry. The nature of the CO2 film is characterized by Fourier transform infrared spectrometry as a function

Low energy electrons can initiate and control chemical reactions through resonant attachment forming an electron-molecule compound state. Recently, it has been theoretically shown that free electrons can also act as catalysts in chemical reactions. W

Resonant formation of H- and O- ions and formation of ethylene glycol (OHCH2CH2OH) on electron impact is seen in the same energy range in condensed molecular films of methanol (CH3OH). This could indicate a new reaction pathway involving bond breakin

Following the recent report of the first identification of methyl acetate (CH3COOCH3) in the interstellar medium (ISM) we have carried out Vacuum UltraViolet (VUV) and InfraRed (IR) spectroscopy studies on methyl acetate from 10 K until sublimation i
