The Shroud of Turin, a linen cloth alleged to be the burial shroud of Christ, has been precisely radiodated to the 14th century. Nevertheless, its status remains controversial. Is the radiodate accurate? Are the blood images seen on the cloth derived from contact of the cloth with a wounded human body? Is it a painting? If not a painting, what is the mechanism of its formation? Some of the latest research attempting to resolve these matters is presented and reviewed.

We have studied the Cu(II), Co(II), and Fe(III) complexes of the antineoplastic drug bleomycin by using electron spin--echo envelope spectroscopy. For all three complexes, nitrogen coordination of the metal ions is demonstrated. For the Cu(II)-- and Co(II)--drug complexes, we have been able to identify imidazole as a metal ligand.

AbstractThe major mass spectrometric fragments of ms‐tetraphenylporphin and ms‐tetra(p‐chloro)phenylporphin are [M  H]+˙ and [M  Cl]+˙, respectively. Metal derivatives of these compounds give a modified characteristic fragmentation pattern with peak groups ending in the ions [M  4H]+˙, [M  ϕ  5H]+˙ and [M  2ϕ  2H]+˙ for the metallo ms‐tetraphenylporphins, and [M  ϕCl  2Cl  3H]+˙ and [M  2ϕCl  Cl  H]+˙ for Mgms‐tetra(p‐chloro)phenylporphin. Deuterated metal derivatives indicate random hydrogen loss from both phenyl and pyrrole carbons. However, metal substituents do not significantly modify the fragmentation pattern in the case of ms‐tetra(p‐methoxy)phenylporphin. These patterns can be explained in terms of aromatic stabilization of the fragmentation products, coupled with charge localization on the π system in the free base, on the metal atom in the metallo derivatives and on the methoxy function in the p‐methoxyphenyl derivative.

AbstractThe mass spectrum of ms‐tetraphenylchlorin was observed to contain a significant porphyrin peak. Attempts to obtain metallochlorin spectra yeilded mainly metalloporphyrin spectra. Sublimation experiments established that the chlorin to porphyrin conversion resulted from electron‐impact excitation and did not arise from thermolysis on the probe or from impurities. In conjunction with previous literature data, this is interpreted as showing that the apparent stability of chlorins with respect to porphyrins is mainly a matter of the activation energies required under specific constraints.
