Zusammenfassung

Es werden die Hauptabsorptionsbanden (N → V Übergang) für eine Serie von Δ4-3-Steroid-ketonen mit C-6-Substituenten diskutiert. Dabei wird versucht, die Lage der Hauptbanden dieser Verbindungen zu erklären. Besonders wird der Einfluss des induktiven Effekts und der von benachbarten Gruppen auf den angeregten Zustand berücksichtigt.
