Absolute 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 کاملDetermination of absolute photoionization cross sections for isomers of C3H5: allyl and 2-propenyl radicals
The photoionization (PI) cross sections of allyl and 2-propenyl radicals to form C3H þ 5 were measured using tunable vacuum ultraviolet (VUV) synchrotron radiation coupled with photofragment translational spectroscopy. At 10 eV, the cross sections were found to be 6.2 1.2 and 5.1 1.0 Mb, respectively. Using these values, the PI efficiency curves for each radical were placed on an absolute scale...
متن کاملThe Crystal Structure and Absolute Configuration of 2 ' - Deoxycytidine Hydrochloride
2'-Deoxycytidine hydrochloride (C9H14N3Q4Cl) was crystallized from water as monoclinic needles, space group P21, with a=6-561, b= 17·659, c=5·125 A, P= 108·08° and two molecules per cell. The crystal structure has been determined by a three-dimensional X-ray diffraction analysis. A complete hemisphere of data (positive and negative values of both hand k) was collected with a General Electric XR...
متن کاملAbsolute configuration of isoeichlerialactone
The title seco-dammarane triterpenoid, C(27)H(42)O(4) (systematic name: 3-{(3S,3aR,5aR,6S,7S,9aR,9bR)-6,9a,9b-trimethyl-3-[(R)-2-methyl-5-oxotetra-hydro-furan-2-yl]-7-(prop-1-en-2-yl)dodeca-hydro-1H-cyclo-penta-[a]naphthalen-6-yl}propanoic acid), has been isolated for the first time from the seeds of Aglaia forbesii. The mol-ecule has three fused rings and all rings are in trans-fused. The two ...
متن کاملAbsolute configuration of micromelin
The title compound {systematic name: 7-meth-oxy-6-[(1R,2R,5R)-5-methyl-4-oxo-3,6-dioxabicyclo-[3.1.0]hexan-2-yl]-2H-chromen-2-one}, C(15)H(12)O(6), is a coumarin, which was isolated from the roots of Micromelum glanduliferum. There are two mol-ecules in the asymmetric unit with slight differences in bond angles. In both mol-ecules, the furan ring adopts a flattened envelope conformation. In the...
