## Abstract A wide variety of push–pull alkenes were studied by means of variable‐temperature ^1^H and ^13^C NMR spectroscopy with respect to the configuration/conformation and the barriers to rotation about partial CC and CN double bonds. For the assignment of the ^13^C NMR spectra especially th

## Abstract Push‐pull alkenes with variable structure were investigated with respect to the influence of the different substituents at the central C,C double bond on the dynamic behaviour of this type of compound. ^1^H and ^13^C NMR spectroscopic investigations were carried out for ketene‐__S__,__S
## Abstract The ^1^H and ^13^C NMR spectra of a variety of differently 2,5,6‐trisubstituted 3,4‐dihydro‐4‐oxo‐2__H__‐thiins (integrated push–pull alkenes) were unequivocally assigned by means of a wide variety of 1D and 2D NMR spectroscopic methods. The NMR parameters thus obtained, together with t
