Dark oxidation of dissolved gaseous mercury in polar ice mimics.
Evidence is presented that due to rate accelerations associated with the operation of the freeze-concentration effect, DGM is oxidized to Hg(2+) ions when frozen in the presence of a variety of materials including hydrogen peroxide, nitrous acid and the sulfuric acid/O(2) couple. Expand
The intrinsic fluorescence spectra of selected pollen and fungal spores
The grasses not only show the common pollen spectral features but also a sharp band at 675–680 nm: this observation demonstrates the presence of chlorophyll-a, which could, in principle, be used in the real-time atmospheric identification of grass pollen, which are known carriers of aeroallergens.

Freeze-induced reactions: formation of iodine-bromine interhalogen species from aqueous halide ion solutions.
The freezing process is shown to induce the formation of the important interhalide ion, IBr(2)(-), which represents a potentially important source of halogen atoms in the polar marine boundary layer. Expand
Cold-surface photochemistry of primary and tertiary alkyl nitrites.
The results point to cold surface processing of alkyl nitrites as a potential environmental source of nitrous oxide and the reaction rates for cis and trans conformer decay were found to be significantly different. Expand
Protonated nitrosamide and its potential role in the release of HONO from snow and ice in the dark.
A joint Fourier transform reflection absorption infrared spectroscopy/thermal programmed desorption (RAIRS/TPD) study has provided good evidence for the existence of protonated nitrosamide (NH₃NO(+))Expand
Ring-expansion of 3-arylinden-1-ones with lithium methylsulphinylmethanide
3,4-Disubstituted 1-naphthols (5a–h) are obtained in 49–89% yield by the reaction of 2,3-disubstituted inden-1-ones (1a–h) with lithium methylsulphinylmethanide
