Conformity evidence

Conformational evidence of thianthrene, thianthrene 5-oxide, and as- and /ra r-thianthrene 5,10-dioxides has been reported by studing FI NMR spectra in different solvents (CD2CI2, toluene-r/g, THE-r/g THE = tetrahydrofuran) and at various temperatures (from 25 to —130°C) (see Section 8.12.4.3) <2005JOC3450>. 

The adsorptive separation of pinenes on Zeolites is reported.303 The C-6 and C-7 13C n.m.r. chemical shifts in bicyclo[3,l,l]heptanes support other known conformational evidence and confirm that cls-pinane and ds-myrtanol (209 X = OH) have a bridged-boat conformation, that trans-myrtanol has a bridged-chair conformation, and that trans-2-pinanol and myrtenol (210 X = OH) have Y-shaped conformations verbenone (211 R R2 = O), and trans-verbenol (211 R1 = H, R2 = OH) give anomalous results which may be due to a conjugation effect the bridged-chair... 

The data indicate that 63% of the benzene molecules which had been excited to the first singlet crossed over to the triplet state. Sato et al., have produced conforming evidence for the Cundall technique as applied to benzene. 

In contrast, the linear polymer, assumes the G+G T conformation. Evidently the ability to form a cyclic tetramer depends on the conformation of the terminal fragment of the macromolecule. When it is in a right position to form the G+G+T conformer then cyclization occurs. When the conformation corresponds to the G+G T arrangement, cyclization is less probable and the linear fragment is fixed by addition of the next monomer molecule. 

Owing to the extensive delocalization of silicon backbone, polysilanes display an intense absorption band in the near-UV region. This absorption band is also strongly coupled with the polymer conformation. Evidence of thermochromism in the solid...
