Absorption Spectra of Nitric Oxide in Solutions
نویسندگان
چکیده
The absorption spectra of nitric oxide in aromatic and aliphatic hydrocarbons, in alcohols and in water were investigated. The experimental results show that the broad structureless absorption bands observed rise from charge transfer between the solvent and NO. Thermochemical data indicate that the solvent-NO interactions are due to contacts in solution without the formation of a stable complex. The charge transfer spectra of NO and 02 solution are compared. The enhancement of singlet-triplet transitions of benzene and the quenching mechanism of triplet states by S O are considered briefly.

Reactions of Haematins and Haemoproteins
1. It is shown that free haematins will react with nitric oxide under certain conditions giving compounds with characteristic absorption spectra. 2. The reactions of nitric oxide with both protohaematin and urohaematin were examined. In acid solution each of these haematins changes colour from reddish brown to a bright red in the presence of nitric oxide, and two strong absorption bands appear ...

Oxido-substituted p-oligophenylenes derivatives of dibenzofuran. are bridge-substituted prolate oligophenylenes. Orthosubstitution leads to the bridging of two phenyl rings and constrains the molecule in the planar configuration. For example, dioxido-p-terphenyl and trioxido-p-quaterphenyl have highly resolved vibronic spectra in n-hexane at 77 K [1], The long-wave absorption and fluorescence s...

A simple, highly sensitive, accurate and selective method for determination of trace amounts of Pb(II) in water samples is presented. A novel Graphene oxide with covalently linked porphyrin solid-phase extraction adsorbent was synthesized by covalently linked porphyrin onto the surfaces of graphite oxides. The stability of a chemically (GO-H2P) especially in concentrated hydrochloric acid was s...
