B Sources of Information

K. H. Brown, Proc. Soc. Photo-Opt. Instr. Eng. 2438, 33 (1995). A good source of information on the new exposure technologies can be found in the Proceedings of the International Conference on Electron, Ion and Photon Beam Technology and Nanofabrication, pubhshed annuaUy in Issue 6 of the Journal of Vacuum Science and Technology B. 

We express our gratitude to Orval E. Jones, George E. Duvall, and Dennis B. Hayes whose unpublished notes have instructed a generation of shock-wave scientists and engineers at Sandia and elsewhere. This excellent source of information figures prominently in this chapter. The figures were skillfully drawn by Kay Lang. 

The primary source of information for enthalpies of formation is J. B. Pedley, R. D. Naylor and S. P. Kirby, Thermochemical Data of Organic Compounds (2nd Ed.), Chapman Hall, New York, 1986. The successor to this volume, J. B. Pedley, Thermochemical Data and Structures of Organic Compounds, Vol. I, Thermodynamics Research Center, College Station, Texas, USA, 1994, has recently been published. We have used values from this latter source when the compounds were not included in the earlier edition. In any case, no reference citation is given except for occasionally referring to either volume as Pedley or merely archival . Where data were... 

These databases are a rich source of information, yet they do not capture an element of interest, namely the biological endpoint there is no searchable field to identify, in a quantitative manner, what is the target-related activity of a particular compound. Such information is important if one considers that (a) not all chemotypes indexed in patent databases are indeed active - some are just patent claims with no factual basis and that (b) not aU chemotypes disclosed as active are equally active, or selective for that matter, on the target of choice. Furthermore, should one decide to pursue a certain interaction hotspot in a given ligand-receptor structure (assuming good structure-activity models are available), it would be very convenient to mine structure-activity databases for similar chemotypes to use as potential bioisosteric replacements. 

Duncanson and Coulson [242,243] carried out early work on atoms. Since then, the momentum densities of aU the atoms in the periodic table have been studied within the framework of the Hartree-Fock model, and for some smaller atoms with electron-correlated wavefunctions. There have been several tabulations of Jo q), and asymptotic expansion coefficients for atoms [187,244—251] with Hartree-Fock-Roothaan wavefunctions. These tables have been superseded by purely numerical Hartree-Fock calculations that do not depend on basis sets [232,235,252,253]. There have also been several reports of electron-correlated calculations of momentum densities, Compton profiles, and momentum moments for He [236,240,254-257], Li [197,237,240,258], Be [238,240,258, 259], B through F [240,258,260], Ne [239,240,258,261], and Na through Ar [258]. Schmider et al. [262] studied the spin momentum density in the lithium atom. A review of Mendelsohn and Smith [12] remains a good source of information on comparison of the Compton profiles of the rare-gas atoms with experiment, and on relativistic effects.

The 13C-NMR spectra of l-arylbenzo[c]pyrylium salts have been investigated in comparison with those of 1-arylnaphthalenes, N-methyliso-quinolinium, and 1-arylisoquinoline derivatives 75ZN(B)943]. The correlation obtained is analogous to relationships found for a series of pyrylium and pyridinium salts, and pyridine derivatives [82AHC(Suppl)]. The, 3C shifts of 1 -aryl-benzo[c]pyrylium salts are also a valuable source of information for ptfa values, aromatic character, and conjugative effects of these compounds (760MR324). 

B. Vibrational Structure of Electronic Transitions 1. Normal vibrations and their symmetry classification An electronic band system belonging to a polyatomic molecule normally contains a large number and variety of transitions in which vibrational quantum changes are superimposed on the electronic jump. The analysis, besides supplementing infrared and Raman evidence of the ground state frequencies, yields values for the fundamental frequencies of the excited state and is one of the principal sources of information as to its structure. 

Table II records the melting points and optical rotations of the 1-gly-cosylpyrimidines. References are also provided for sources of information on (a) their ultraviolet and infrared absorption spectra, and (b) their paper chromatography.
