The energetic thresholds for ion-pair photodissociation of diatomic oxygen fO2 1 hn ! O 1 OsP3y2, P1y2dg were measured using a novel technique. The technique depends on the production and selective detection of highly vibrationally excited ion-pair states which last for at least 5 ms following single photon excitation from the ground electronic state of O2. These ion-pair states are analogous t...

Magnetic-sensitive radical-ion-pair reactions are understood to underlie the biochemical magnetic compass used by avian species for navigation. Recent experiments have provided growing evidence for the radical-ion-pair magnetoreception mechanism, while recent theoretical advances have unravelled the quantum nature of radical-ion-pair reactions, which were shown to manifest a host of quantum-inf...

Simple, rapid and sensitive spectrophotometric methods were developed for the determination of chlorodiazepoxide drugs in pharmaceutical dosage forms. This method is based on ion pair and charge transfer complexation reactions. The method is based on the reaction of the chlorodiazepoxide drug with Mo(V)–thiocyanate in hydrochloric acid medium followed by an extraction of the coloured ion-pair w...
