Graphical Abstract: The pseudo Jahn-Teller effect is employed to explane the origin of structural distortions of carbonyl fluoride, diazene and ketene molecules in the lowest singlet and triplet excited states. It was shown that in all the cases the distortions of the molecules in the excited states are due to the vibronic mixing of considered states with the appropriate by symmetry higher-lying excited states.
