MetadataShow full item record
Raman scattering, fluorescence, visible absorption, ultraviolet absorption, and infrared absorption spectra of s-tetrazine-d and s-tetrazine-d„ were observed. Previously o 2. unreported fundamental vibrational bands were found. Vapor phase fluorescence was observed for the first time. Absorption band structure was found in the 300-400 nm region of solutions and a corresponding vapor phase absorption was observed. The high resolution visible absorption spectrum of s-tetrazine-d 2 is reported for the first time. The chemistry of the thermal and photochemical decomposition of tetrazine vapor was investigated including studies of thermochemical parameters, quantum yield, and decomposition products. A quantitative evaluation was made on the temperature dependence of selected lines in the visible absorption spectrum. Absorption coefficients, solubilities in various solvents, vapor pressure, mass spectra, and far infrared spectra were among the other properties investigated. The Raman spectrum of N ,N-dimethylformamide is reported.
