cze	Obor platnosti Hammettovy rovnice: kyselost substituovaných ethynylbenzenů	Byly počítány acidity 19 meta- a para-substituovaných ethynylbenzenů a korelovány podle Hammettovy rovnice s vypočítanými aciditami stejně substituovaných benzoových kyselin. Byly nalezeny charakteristické odchylky od Hammettovy rovnice pro para substituenty, a to jak pro akceptory tak pro donory.

eng	Range of validity of the Hammett equation: acidity of substituted ethynylbenzenes	Acidities of 19 meta- and para-substituted ethynylbenzenes were calculated and correlated within the framework of Hammett equation with the calculated acidities of equally substituted benzoic acids. Characteristic deviations from the Hammett equation were found pof para-substituents, both for acceptors and donors.
