Chromophoric systems based upon through-bond interaction: Chromophoric systems based upon through-bond interaction. IV. Intramolecular charge-transfer interaction via three sigma bonds.Several substances are used for example 62702-80-1 and 42949-24-6 which are their cas registry numbers. Pasman, P.; Verhoeven, J. W.; deBoer, Th. J. (Lab. Org. Chem., Univ. Amsterdam, Amsterdam, Neth.). Tetrahedron, 32(22), 2827-30 (English) 1976. CODEN: TETRAB. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Ketones contg. a .beta.-substituent with a readily ionizable lone pair or .pi.-electrons were studied by UV spectroscopy. When the geometry favored through-bond interaction between the carbonyl group and the .gamma.-substituent, a sigma-coupled transition was obsd. in the near UV region. Replacement of the carbonyl group by more electroneg. systems, e.g., C(CN)2, enhanced the intensity of the sigma-coupled transition and shifted it bathochromically. These phenomena are interpreted as resulting from the charge-transfer character of the sigma-coupled transition. Intensity borrowing from locally excited states plays an important role in detg. the intensity of this sigma-coupled transition. .
