Photochemically induced ring opening is responsible for the photochromism observed in indolinespiropyrans. Factors affecting the photostability of these spiropyrans and their behaviour in organised molecular assemblies have been investigated, and new idolinespiropyrans with 7r-acceptor substituents in position 8 have... 

At high surfactant concentrations (above the c.m.c.), micelles of ionic or nonionic surfactants can produce organised molecular structures within the liquid film [21, 22]. This will provide an additional contribution to the disjoining pressure. Thinning of the film occurs through a stepwise drainage mechanism, referred to as...

The book is organised so that some of the techniques discussed in later chapters refer to material discussed earlier, though I have tried to make each chapter as independent of the ofhers as possible. Some readers may therefore be pleased to know that it is not essential to completely digest the chapters on quantum mechanics and molecular mechanics in order to read about methods for searching conformational space Readers with experience in one or more areas may, of course, wish to be more selective. 

The organizing committee extends a cordial invitation to participate in International conference on Analytical Chemistry and Chemical Analysis (AC CA-05) which is hold in scenic city of Kyiv, Ukraine, from. Septemher 12 to 18,2005. Tills conference belongs to die series of Ukrainian conferences in analytical chemistry established in 1970 by Ukrainian chemical society and chemical division of Ukrainian Academy of. Sciences. AC CA-05 is a 7 conference in analytical chemistry in Ukraine and it is dedicated to the centenary of the birth of the outstanding Ukrainian scientist, Anatoly K. Babko for his expertise in analytical chemistry and in the chemistry of complex compounds. Tlie current conference is organised by Analytical Scientific Council at Academy of Sciences of Ukraine under collaboration with European Association for Chemical and Molecular Sciences (EuClicMS) and sponsored by Intemational Union of Pure and Applied Chemistry (lUPAC) and by the Intemational Association for the Promotion of Co-operation with Scientists from the New Independent States of the Eormer Soviet Union (INTAS).

XANES, which can be used to determine molecular structure and orientation of chemisorbed molecules on well-characterised single-crystal surfaces and is able to discriminate between the same atoms in different bonding situations, has been used to examine the supramolec-ular organisation adopted by the dye Reactive Red 3 1 physisorbed and chemisorbed on to cotton and cellophane substrate materials [315]. A distinct difference in the nature of the dye/cotton interaction was observed for different preparative methods. The mode by which...

The formation of host-guest inclusion compounds in crystals (or in highly ordered membranes or other biological structures) is a phenomenon more organised than simple co-crystallisation of a pair of substances. The special characteristic of inclusion crystallisation is a constant identity of one member in a series of pairs, this member thereby being identified as host, and a constancy of structure type (but not necessarily dimensions) for the host. The higher molecular organisation involved in inclusion... 

Another crucial problem for any neurochemical model is cause and effect. Neuroleptics have a high affinity for dopamine receptors, particularly the D2-subtype. There is also a highly significant positive correlation (r > +0.9) between this receptor binding and their clinical potency (Seeman, 1980). But, this does not necessarily implicate elevated dopamine levels as the cause of schizophrenia. Moreover, blockade of dopamine receptors happens very rapidly, whereas clinical benefits are only seen after chronic treatment. Rose (1973) has criticised the reductionist statement that an abnormal biochemistry causes schizophrenia because it relates cause and effect at different organisational levels (namely, the molecular and behavioural). But, while it can be legitimate to discuss cause and effect at the same level that chlorpromazine blocks dopamine receptors (one molecule altering the response of another), it is not valid to infer that increased dopamine activity causes schizophrenia. Put another way ...
