## Abstract A wide variety of pushโ€“pull alkenes were studied by means of variableโ€temperature ^1^H and ^13^C NMR spectroscopy with respect to the configuration/conformation and the barriers to rotation about partial C๏ฃฟC and C๏ฃฟN double bonds. For the assignment of the ^13^C NMR spectra especially th

## Abstract The phenylselenenylmenthane and โ€menthene derivatives 1โ€“4 were studied in terms of ^1^H and ^13^C signal assignments, conformational analysis and also complexation shifts (ฮ”ฮด) and dispersion effects (ฮ”ฮฝ) observed when nonโ€racemic (ca 2 : 1) mixtures of the chiral selenides were exposed
