The geometry of N-benzalaniline

Reaction pathways for the photochemical conversion of o-substituted benzylideneanilines to azoles

“…(dm -dmQa) and AEmqa/AEm corresponding to n = 7 [or 10] we estimate dm to be 98.1°( or 98.9°) and A2?b to be 5.7 kcal/mol (or 4.6 kcal/mol). These values compare with previous estimates by Holmes, et al, (field B) of 91.4°and 15.3 kcal/mol in which a guess of the effect of anharmonicity was made, but in which F67 was neglected since it was not known at the time.15 A more recent value of 3.0 kcal/mol based on an observed bending anharmonicity in VF5 scaled to PF5 has also been estimated by Holmes.…”

The optical path length for the monitoring light was 10 cm.…”

Poly(Schiff base)s Containing 1,1′-Binaphthyl Moieties: Synthesis and Characterization

“…Many structural studies such as X-ray analysis, [37] UV, [38] 1 H NMR [39] and photoelectron spectroscopy, [40] IR and Raman spectra [41] have implied the non-planar conformation of the azomethine compounds in solid or solution phase. For instance, X-ray analysis of benzylideneaniline has shown that the aniline ring is twisted out of the C1N2C1C plane by 55 8, while the benzylidene ring is twisted by 10 8, and this agrees with its anomalous UV spectrum compared with the planar stilbene and azobenzene molecules.…”

Nuclear magnetic resonance spectrometry

“…Investigations on the complex layer of alkylbenzenealuminum chloride-hydrogen chloride (1085), the benzene nucleus as a probe for the -electron structure of annulenes (1086), interaction between dibenzacridines and benzene (1087), geometry of N-benzalaniline (1088), and the structure of N-benzalanilinium ions (1089) have been completed. The effects of electronic buttressing on the conformations of some O-disubstituted benzenes (1090) and the rationalization of procedures for processing data obtained from NMR studies (1091) have been discussed.…”
