1.5 Sintesi del progetto di ricerca
ENERGETICS AND DYNAMICS OF COMBUSTION INTERMEDIATES
This proposal describes a collaboration between the University of California, San Diego (UCSD) Department of Chemistry and Biochemistry (Continetti) and the Department of Chemistry at the Univ. La Sapienza (Stranges) that will apply complementary state-of-the-art experimental techniques to understanding the energetics and dynamics of combustion intermediates. The chemistry of transient combustion intermediates is central to our understanding of the efficiency of fossil fuel combustion and its environmental impacts, including the formation of soot and other aerosols. At UCSD, pioneering work using negative ion precursors and fast beam translational spectroscopy has been carried out to characterize neutral alkoxy radicals [1,2] and most recently the essential hydroxycarbonyl radical (HOCO), the intermediate in the fundamental reaction of OH + CO ---> H + CO2 [3,4], using the technique of Photoelectron-Photofragment Coincidence (PPC) Spectroscopy. At La Sapienza, Prof. Stranges has established a state-of-the-art laboratory using Photofragment Translational Spectroscopy (PTS) with universal mass-spectrometric detection, and has made a number of important discoveries concerning the photochemistry of the allyl radical [5-7]. This collaborative effort will be initiated with the visit of Professor Continetti to La Sapienza from January – April 2013, and will lay the foundation for further exchange of students and postdoctoral fellows as well as the PI’s, as time permits, in the future.
The complementary approaches to the study of radical photochemistry and dissociation dynamics available in the two laboratories will provide a more complete understanding of the role played by the radicals in complex systems, such as combustion and atmospheric oxidation. The PTS experiments at La Sapienza allows the probing of the dissociative states of hydrocarbon radicals in photodissociation experiments in the UV (248 nm, 5 eV). The focus of experimental efforts during the period of this collaboration will turn to more complicated prototypical hydrocarbon radicals, in particular the n-propyl radical and the 2-methyl-allyl radical. Once clean sources for these radicals are developed, as discussed further below, the capability of the Rome PTS spectrometer to examine with excellent mass resolution the dissociation pathways using the universal mass spectrometric detection approach will provide some of the first information available on the photochemistry of these radicals to date, with the exception of a prior study on H-atom elimination from the n-propyl radical . Complementary experiments on the 2-methyl-allyl radical will be initiated during this period in Continetti’s laboratory at UC San Diego. Lineberger and co-workers have already shown that the 2-methyl-allyl radical anion can be generated in the gas-phase, and the electron affinity of the radical has been measured to be 0.5 eV . With the light sources (up to 4.8 eV) available in the Continetti group, photodetachment of the radical anion will allow preparation of excited states nearly as high as the photoabsorption from the ground state neutral radical at 248 nm used in the PTS experiements. This will yield complementary insights into optically forbidden states (accessible in anion photodetachment) and also providing an alternative route to examining H-atom elimination pathways that are more difficult to study in the PTS experiment owing to large background signals in the mass spectrometer at m/e = 1. These experimental efforts in the two laboratories, conducted in concert and catalyzed by the presence of Continetti at La Sapienza will constitute an important advance in the study of these prototypical free radicals.
An additional direction for the PTS experiments in Rome will be the extension to oxygenated species, including the tert-butoxy (CH3)3CO and allyloxy C3H5O radicals. Alkoxy radicals are essential intermediates in the oxidation of hydrocarbons. In addition, oxygenated carbon radicals are becoming increasingly of interest as the use of biofuel sources, including ethanol, butanol and long-chain saturated and unsaturated acids and esters. Oxygenated species in general are amenable to study using negative ion precursors, owing to the stability of alkoxide anions, so a number of experiments have been carried out using PPC spectroscopy at UCSD, as noted above. However, the challenge with those experiments is indeed the stability of the alkoxide anions. Alkoxy radicals have significant electron affinities, in the 1.8 – 2.5 eV range, so photodetachment of the corresponding alkoxide anions even at 258 nm (4.8 eV) can only produce radicals with ~ 2.5 eV of internal excitation, considerably below the excitation energies available by photoabsorption from the radical ground state with the light sources available in the laboratory at La Sapienza. The key to carrying out experiments on the oxygenated species in Rome will be the demonstration of bright and stable source for these oxygenated radicals, as further discussed below.
In summary, this proposal describes a complementary program of research on prototypical free radicals of interest in atmospheric oxidation, combustion and the combustion of oxygenated biofuels. Using PTS spectroscopy in Rome, the photochemistry of alkyl and alkenyl radicals will be characterized during the visit of Professor Continetti of UCSD. In addition, complementary experiments involving the dissociative photodetachment of the 2-methyl-allyl radical anion will be carried out in Continetti’s laboratory during this period. In addition, research will be carried out in Rome to extend the PTS experiments to oxygenated radicals that have been studied, at lower excitation energies, using PPC spectroscopy on the corresponding anions at UCSD. These PTS experiments will extend our knowledge of the chemistry of these reactive species to higher lying excited states for the first time.
