The deuterium and proton NMR spectra of samples of 4-ethoxy-4'-cyanobiphenyl dissolved in the nematic liquid crystal 4-hexyloxy-4'-cyanobiphenyl have been analyzed to yield quadrupolar splittings and dipolar couplings.The data are compared with values calculated for three models for the conformations adopted by the ethoxy group relative to the attached phenyl ring.These models are (a) a set of four, symmetry-related structures, (b) discrete, minimum-energy structures generated by jumps about the C4-O, O-C7, and C7-C8 bonds, and (c) the same as (b) except that a continuous potential is adopted for the motion about the O-C7 bond.
Raman spectroscopy of n-pentyl methyl ether and deuterium labelledanalogues
Bowen, Richard D.,Edwards, Howell G. M.,Farwell, Dennis W.,Morgan, Sara E
experimental part, p. 1725 - 1734 (2012/04/04)
The Raman spectra of n-pentyl methyl ether, C5H 11OCH3, and six selectively deuteriated analogues arereported and discussed. Correlations between the observed ν(sp 3CH)stretching and bending bands and the position of the deuterium atoms in thealkyl chain are developed and refined. Similar progress is possible inassociating specific skeletal vibrations with bands in the Raman spectra. Therelevance of this study to improving the assignment of bands in the Ramanspectra of larger systems of biological interest is highlighted. Copyright
Intermediacy of ion neutral complexes in the fragmentation of short-chain dialkyl sulfides
Filsak,Budzikiewicz
, p. 601 - 610 (2007/10/03)
The main fragmentation processes after electron ionization of butyl methyl and butyl ethyl sulfides are rationalized by the intermediacy of the ion neutral complex [RSH · methylcyclopropane](+·) as demonstrated by extensive labeling and collision activation studies.
