Abstract
The electron spectra of 1-indanone (I), 1-tetralone (II), phthalide (III), homophthalide (IV), 3,4-dihydroisoquinoline (VII), and 3,4-dihydroisoquinolinium (VIII) compounds, substituted by electron donating groups (hydroxy, methoxy or methylenedioxy groups) on the aromatic nucleus, resemble when the electron donors are at the same distance from the electron accepting substituent. In the compounds VII and VIII, the electron spectra were measured in ethanol at acidic and alkaline pH, and the change in the spectra of the compounds VIII in alkaline medium was clarified.
