[Oscillation spectra of metal-porphyrin dication spectra]. / Kolebatel'nye spektry dikationov metall-porfirinov.

Spectra of resonance spontaneous combination scattering (RSCS) of dications of metal--derivatives of tetraphenyl and ethioporphyrine (Ni-TPhP, Cu-TPhP, Cu-EP and VO-EP0 and IR-spectra of absorption of Ni-TPhP and Cu-EP dications were obtained. It was found that transformation of porphyrine neutral molecules into dications is accompanied with the appearance of new absorption bands in IR-spectra analogs of which are in RSCS spectra of dications. In some cases it points to the disturbance of alternative prohibition to oscillative transitions and to structural changes which result in the loss of symmetry centre by the molecule when it is transformed into the dication. A comparison of RSCS spectra of dications and dianions of VO-EP suggests that they have different structure.

[Absorption spectra and structure of sublimated layers of etioprophyrin and its metal derivatives]. / Spektry pogloshcheniia i struktura sublimirovannykh sloev étioporfirina i ego metalloproizvodnykh.

It has been established by means of electron and oscillation absorption spectra that the structure of sublimated layers of ethioporphyrin and its metal-derivatives depends on sublimation conditions. When sublimation was performed in a vacuum the molecules were located parallel to the base surface, in the presence of gase--at an angle, near to the right one, interlocation (and hence interaction) of molecules in the layers of different structure conditions the differences in their spectral characteristics and a peculiar anisotropy of layers. The later consists in the difference of optical properties in longitudinal and perpendicular directions to the layer surface.
