VELASCO IBARRA, Luis et al. Relación lineal de energías libres en la fragmentación de 1,3-ditianos. Rev. Soc. Quím. Méx [online]. 2001, vol.45, n.4, pp.149-151. ISSN 0583-7693.

A free energy study for a serie of 1,3-dithianes whith an aromatic substituent in position two was carried out. Applying the McLafferty equation to the corresponding mass spectra data, a lineal correlation was observed; thus the effect of the substituent over the fragment stability of [M-74 ]+· was demonstrated.

Palavras-chave : McLafferty correlation; S*S-acetals; mass spectra; linked-scans.
