Morton}, title = {Structures of products from positive ion-molecule reactions by means of vibrational spectroscopy}, abstract = {Examples of various approaches to determining gaseous ion structures are described. Two cases are presented in which infrared multiple photon dissociation (IRMPD) spectroscopy provides characteristic information. Comparison with OFT-calculated normal modes differentiates isomers. The IRMPD spectrum of the even-electron C8D8F+ product ion from the ion-molecule reaction of CF3+ with perdeuterated acetophenone exhibits a degree of resolution sufficient to identify C6D5CFCD3+ and rule out ring-fluorinated isomers. The dimerization of phenylacetylene with its molecular ion has been explored, with the conclusion that a mixture of product ions is formed. The best match to the experimental spectrum is achieved by superimposing the bands calculated for ionized 1-phenylazulene and ionized 1,2-diphenylcyclobutadiene.}, year = {2010}, journal = {European Journal of Mass Spectrometry}, volume = {16}, number = {3}, pages = {313-319}, isbn = {1469-0667}, url = {://000279325900008 }, note = {ISI Document Delivery No.: 618BJTimes Cited: 0Cited Reference Count: 23Sp.
