With the passing of Prof. Robert C. Dunbar on 31 October 2017, the field of ion chemistry lost one of its modern heroes. Throughout his career in mass spectrometry, two of his main research interests involved the interaction of trapped ions with elec

We present the gas-phase infrared spectra of the phenyl cation, phenylium, in its perprotio C$_6$H$_5^+$ and perdeutero C$_6$D$_5^+$ forms, in the 260-1925 cm$^{-1}$ (5.2-38 $\mu$m) spectral range, and investigate the observed photofragmentation. The

We report on a common fragment ion formed during the electron-ionization-induced fragmentation of three different three-ring polycyclic aromatic hydrocarbons (PAHs), fluorene (C13H10), 9,10-dihydrophenanthrene (C14H12), and 9,10-dihydroanthracene (C1

Infrared multiple photon dissociation spectrum of protonated bis(2-methoxyethyl) ether obtained with a tunable CO2 laser

Autor: Wright L. Pearson, John R. Eyler, N. A. Horenstein, Y. Bozai, Mohammad Ehsan

Publikováno v: Physical Chemistry Chemical Physics. 17:25877-25881

A moderate-resolution infrared multiple photon dissociation (IRMPD) spectrum of protonated bis(2-methoxyethyl) ether (diglyme) was obtained using a grating-tuned CO2 laser. The experimental spectrum compares well with one calculated theoretically at
