Abstract

Individual Infrared spectroscopic absorption bands in the double bond region have been assigned to specific, nonequivalent Β-ketoenamine structural fragments, i.e., to atomic groups in which the carbonyl is included in a cyclic oxoindenodihydropyridine system or to a ketoenamine group with a nonrigid carbonyl-containing substituent.
