Adequate theoretical treatments must take account of the persistent effects of such contingent historical events whenever they are relevant—as they generally are in chemistry. 展开 关键词: Synchronic Diachronic Isomers Chemical structure W*-algebra Allene Propyne Propadiene Philosophy of chemistry Metastable...
Poly[l-trimethylsilyl-l-propyne](PTMSP) and its modification (l-Trimethylsilyl)-l-propyne -(l-Pentamethyldisilyl)-l-propyne Copolymer(TMSP-PMDSP) (5 mol% PMDSP) dense membranes was exterted to probe the effect of the chemical structure of membrane materials on pervaporation(PV) characteristics...
Ab initio MP2 calculations with several basis sets proved the existence of a stable benzonitrile dimer with a planar structure and a short contact between the H atom of one molecule and the N atom of another. The structure is greatly stabilized by attraction between the neighboring oppositely dir...
