Das Laduiigsverteiluiigsproblem wird mittels des Substitueiite~i-Eiri~uss~~ auf die Dipolmomente, 31P-NMR-, 1R-und UV-Spektren von p-stindig substituierten Phenyl-diathylund Phenyl-bis-[p-mcthoxy-phenyll-phosphinsulfiden experimentell untersucht sowie dic Wechselwirkung der Substituenten mit der P=S-Gruppe empirisch diskutiert.

The interaction between the substituents and the PzS-group is discussed empirically.
