Spettri ultrarossi di strati sottili iso—orientati di acido ortoborico HBO

Alessandro Bertoluzza;  G.B. Bonino;  Antonia Morelli Bertoluzza — 1970

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti

Orthoboric HBO thin films are prepared by a new tecnique consisting in vaporizing and condensing the orthoboric acid directly on the windows of an i.r. cell under vacuum. The i.r. spectra of the thin films are reported and their iso-oriented nature is indicated by the lack of the absorption i.r. bands due to O-H and BO out-of-plane vibrations. Some considerations on thin film structure are then stated.

Indagine spettrometrica ultrarossa di dischi di KBr ottenuti dal materiale fuso a contatto e fuori il contatto della fiamma metano-aria

Alessandro Bertoluzza;  G.B. Bonino;  Antonia Morelli Bertoluzza — 1970

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti

The i.r. spectra of KBr disks are recorded on potassium bromide fused into and outside the contact of a methane-air flame. In the first case more absorption i.r. bands have been observed and they have been attributed to CO, CO and HCO (unstable) adsorbed species. A mechanism of CO ions formation is proposed and it contemplates a reaction between CO of the flame and OH ions formed onto surface of the material fused into the contact of the flame. Some...
