Notes:
The mass spectra of twenty-eight monosubstituted trans-stilbenes in ortho, meta, para and alpha positions with —N(CH3)2, —NH2, —OCH3, —OH, —Br, —Cl, —F, —CH3, —COOH, —CN and —NO2 groups as substituents have been studied. A detailed fragmentation pathway is given for stilbene. This fragmentation, characteristic for most of the substituted stilbenes, takes place either from the molecular or from the [M - Substituent] ion. In o-nitro-, o-methoxy-,α-carboxyl- and α-methylstilbene, however, rearrangement reactions prior to fragmentation influence the fragmentation pattern.
