Autor: Mohammed A. Nabeerasool, Andrew K. Campen, David A. Polya, Nigel W. Brown, Bart E. van Dongen

Publikováno v: Water, Vol 7, Iss 6, Pp 3057-3071 (2015)

Metaldehyde is a selective pesticide applied to control snails and slugs and which, particularly when application rates are high and during periods of high rainfall, may find its way into water courses, some of which may be used as drinking water sup

Applications of polymer films and Nujol mulls to spectroscopic studies at low temperatures: electronic spectra of chromate, dichromate, chlorochromate, manganate and permanganate ions at 12–77 K

Autor: Andrew K. Campen, Mario A. Ollino, Antony J. Rest

Publikováno v: Inorganica Chimica Acta. 180:133-138

Electronic absorption spectra have been obtained for chromate, dichromate, chlorochromate, manganate and permanganate ions in argon and dinitrogen gas matrices, poly(vinyl alcohol) films and Nujol mulls at c. 12 and 77 K. All the ions showed well res

Luminescence spectra and lifetimes of tris-(2,2′-bipyridine)ruthenium(II) dichloride and potassium hexacyanochromate(III) in polymer films and hydrocarbon mulls at approximately 77 K: evaluation of alternative host media for studying unstable species in photochemical reaction pathways originating from non-volatile substrates

Autor: Keitaro Yoshihara, Antony J. Rest, Andrew K. Campen

Publikováno v: Journal of Photochemistry and Photobiology A: Chemistry. 55:301-317

Emission, polarized emission and luminescence lifetime measurements were carried out for [Ru(2,2′-bipyridine)3]Cl2 in poly(vinyl alcohol) films, Nujol mulls and poly(propylene oxide) mulls at approximately 77 K in order to evaluate the degree of mo

Photochemistry of pentacarbonyl(cyclohepta-1,3,5-triene-7-carbonyl)manganese and pentacarbonyl(σ-cycloheptatrienyl)rhenium in frozen gas matrices at ca. 12 K: infrared spectroscopic evidence for carbon monoxide ejection with concomitant polyene ring hapticity changes

Autor: Antony J. Rest, Ramaier Narayanaswamy, Andrew K. Campen

Publikováno v: J. Chem. Soc., Dalton Trans.. :823-832

Infrared spectroscopic evidence, including 13CO labelling and energy-factored force-field fitting, is presented to show that once a CO ligand has been photochemically ejected from [Mn(C7H7CO)(CO)5] to yield [Mn(σ-C7H7)(CO)5]via a 16-electron species
