چکیده
The present contribution reports on the analysis of the high resolution FTIR spectra of the only two IR-active parallel fundamentals v u and v12 of the isotopomers 1 2 C 3 1 4 N 3 H 3 , 1 3 C 3 1 4 N 3 H 3 , 1 2 C 3 1 5 N 3 H 3 , C 3 1 5 N 3 H 3 and 1 2 C 3 1 4 N 3 D 3 , respectively, of 1,3,5-triazine. The molecular constants of the ground state and the upper states u u = l and vl2 = \, respectively, for all molecules under consideration are listed. The enhancement of the Pand the depletion of the R-banches, observed in the v n bands of all non-deuterated isotopomers, is discussed, and the Herman-Wallis constants obtained are given.

Investigation on the Stability of Derivative Melam from Melamine Pyrolysis under High Pressure
Although various kinds of carbon nitride precursors have been proposed, s-triazine-based structures are hardly reported because of their unfavorable energy, higher than that of heptazine-based ones. In this study, we investigate the thermal stability of s-triazine-based melam processed at a high pressure of 5 GPa and a temperature of 400-700 °C and complete the analyses of the composition and s...
متن کاملBET, thermal degradation, and FTIR spectras of triazine polyamine polymers
Here we show effect of the polyamine polymer chain length to BET isotherms. According to IUPAC classification [1], all three polymers are fitting type 1 physical adsorption isotherm with H3 hysteresis (except for EDA having H2 hysteresis). Moreover, TG and TGA analysis of polymers triazine-ethylenediamine (EDA) and triazine-triethylenetetramine (TETA) are provided. Due to the similarities of th...

Positionally dependent fractionation factors for the photolysis of isotopomers of N20 in natural abundance have been determined by high resolution FTIR spectroscopy at three photolysis wavelengths. Fractionation factors show clear lSN position and photolysis wavelength dependence and are in qualitative agreement with theoretical models but are twice as large. The fractionation factors increase ...
