Найти книгу: "Photochemical Key Steps in Organic Synthesis"

Basic laboratory technique in organic chemistry plays a vital part in the education of chemistry students. This textbook contains a collection of multistep experiments that all feature one or two photochemical key steps. More than 40 researchers active in the field of organic photochemistry have contributed their favorite experiments for this unusual and modern textbook. In addition, a general section discusses reaction control, the interpretation of UV spectra, quantum yields and chemical yields, and gives information on solvents, lamps, filters, and vessels. The experiments chosen fulfil the following criteria: * starting materials are cheap and readily available * the necessary photochemical equipment is available in (most) institutes * products prepared are useful for further syntheses * the light reaction is efficient. 'Photochemical Key Steps' is a source book of new ideas for supervisors of lab courses and gives students the opportunity to learn about modern techniques in the laboratory and about the important role photochemistry plays in organic synthesis.

A level 4 Oxford Bookworms Library graded reader. Retold for Learners of English by Nick Bullard. 'I turned on the light, but there was nobody there. Then I saw something in the corner that made my blood turn cold. Scudder was lying on his back. There was a long knife through his heart, pinning him to the floor.' Soon Richard Hannay is running to his life across the hills of Scotland. The police are chasing him for a murder he did not do, and another, more dangerous enemy is chasing him as well – the mysterious 'Black Stone'. Who are these people? And why do they want Hannay dead?
