“…In Figure 7 are shown in the gas-phase spectra of tyrosineglycine, phenylalanine-tyrosine, and phenylalanine-leucine performed by laser-induced vaporization. The basic tyrosine spectrum has its origin around 282 nm; however, the tyrosine aromatic ring tr-* absorption is strongly shifted to the UV by other amino acids, which appear to act as electron-withdrawing groups in this case (12). Thus strong absorption bands are observed around 220-240 nm for these peptides, but only a very weak absorption is present at ~280 nm.…”

“…Second, there is some preliminary evidence that succinic acid may undergo non-photochemical decomposition under the vapor-phase deposition conditions [5] used in these experiments.…”

“…This ash, and the subfractions obtained from it, have been used extensively in studies of the photochemical transformation of PAHs [4]. In all cases, compounds were deposited onto the fly ash from the vapor phase, and photochemical experiments proceeded via illumination of samples for 24 hours with radiation from a xenon lamp source, as described in previous work from this laboratory [4,5]. The results are compiled in Tab le I.…”

“…Hughes et al (75) exposed coal fly ash, enriched with PAH through vapor-phase adsorption (104), to gaseous concentrations of 100 ppm of SO2 and S03. They observed no reaction with SO2, while many reaction products were observed with S03.…”
