Studies in the Organic Solid State
This paper describes an approach to crystal engineering based on designing and analyzing hierarchical levels of crystal l ine architecture. The system under study consists of 1:1 co-crystals of melamines and barbituric acids that selfassemble into crystallographically infinite hydrogen-bonded tapes. The formation of structural elements can be rat ional ized and control led using famil iar molec...
متن کاملSolid state and solution nitrate photochemistry: photochemical evolution of the solid state lattice.
We examined the deep UV 229 nm photochemistry of NaNO(3) in solution and in the solid state. In aqueous solution excitation within the deep UV NO(3)¯ strong π → π* transition causes the photochemical reaction NO(3)¯ → NO(2)¯ + O·. We used UV resonance Raman spectroscopy to examine the photon dose dependence of the NO(2)¯ band intensities and measure a photochemical quantum yield of 0.04 at pH 6...
متن کاملAbsolute structure and absolute configuration.
Fundamental notions concerning absolute structure and absolute configuration, and their determination from single-crystal diffraction measurements, are presented and reviewed. A glossary of terms with definitions useful in this field is provided. For absolute structure and its determination, the separate but interacting influences of the structure and the inversion-distinguishing power of an X-...

متن کاملMechanistic Organic Photochemistry
In this chapter we are concerned with the mechanisms of organic photochemical reactions. Two important features of mechanisms are the correlation of molecular structure with reactivity and the investigation and establishment of the details of the elementary steps involved in a photochemical process as *R proceeds to P. We shall be concerned with the experimental tools for characterizing the str...
