1. Propetamphos is an organophosphorus compound. Technical grade propetamphos consists of 4 isomers, 2 geometric (cis and trans) isomers and 2 optical (Sand R-)isomers. The cis form predominates as the active ingredient, usually exceeding 90% w/w of the technical material. From analogy with the chiral separation of propetamphos-oxon, cis-propetamphos is a racemate of equal proportions of the Sa...

The pine sawfly Diprion jingyuanensis Xiao and Zhang (Hymenoptera: Diprionidae) is a serious pest of Pinus tabulaeformis Carr. in the Shanxi, Gansu, Inner Mongolia provinces P. R. China. sex pheromone D. was shown to be propionate ester 3,7-dimethyl-2-tridecanol. Virgin females contained an approximate 1:3 blend precursors erythro-(2S,3S,7R/S 2R,3R,7R/S)-3,7-dimethyl-2-tridecanol threo-(2S,3R,7...

Coinage metal atom (Cu, Ag, Au) reactions with SO2 were investigated by matrix isolation infrared absorption spectroscopy and density functional theory electronic structure calculations. Both mononuclear complexes M(η(1)-SO2) (M = Ag, Au) and M(η(2)-O2S) (M = Ag, Cu) were observed during condensation in solid argon or neon. Interestingly, the silver containing mononuclear complexes are intercon...

We have examined the photobehavior of a set of isomers of 2-pyranone-annulated stilbenes (6-styrylcoumarin 1, 7-styrylcoumarin 2, 4-methyl-6-styrylcoumarin 3, and 4-methyl-7-styrylcoumarin, 4) in their crystalline phases. While the cis isomers of 1-3 undergo cis-->trans photoisomerizations in the solid state, cis-4 and the trans isomers of 1-3 do not; the trans isomer of 4 undergoes photo-induc...

The gas chromatography-flame ionization detector equipped with a higher polarity column (i.e., SP-2560) has often been used for the quantification of trans-fatty acids in food. In particular, AOCS Ce 1h-05, the official method of the American Oil Chemists' Society (AOCS), is a highly effective method to separate the isomers of trans-fatty acids. In this study, the resolution behavior and the re...

The ability of a series of 18 carbon acetylenic fatty acids to fulfill the unsaturated fatty acid requirements of Escherichia coli and Saccharomyces cerevisiae was investigated. Despite their high melting points (greater than 40 degrees C), several isomers of the acetylenic fatty acids were as efficient or more efficient in supporting growth than the analogous fatty acid having a cis-double bon...

2D [(1)H, (15)N] HSQC NMR spectroscopy has been used to monitor the reaction of fully (15)N-labelled [{trans-PtCl(NH3)2}2(μ-trans-Pt(NH3)2{NH2(CH2)6NH2}2)](4+) (BBR3464 ((15)N-1)) with the 14-mer duplex (5'-{d(ATACATG(7)G(8)TACATA)}-3'·5'-{d(TATG(18)TACCATG(25)TAT)}-3' or I) at pH 5.4 and 298 K, to examine the possible formation of 1,4 and 1,5-GG adducts in both 5'-5' and 3'-3' directions. In a...

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS) was applied to analyses of biomolecules, such as proteins, peptides and oligosaccharides.1–5 The post-source decay (PSD) fragmentation of peptides and oligosaccharides occurred at peptide bonds and at glycosyl linkages in MALDI-MS, respectively. Thus, the PSD mass spectra are useful for the sequencing of ...

Hindrance factors for $K$-forbidden $E2$ decays from multiquasiparticle isomers are analyzed in relation to mixing matrix elements that often associated with chance near degeneracies, and a functional relationship is established. Focusing on effective $\mathrm{\ensuremath{\Delta}}K=6$ three-quasiparticle isomers, significant configuration dependence demonstrated.
