One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 123-32-0, Name is 2,5-Dimethylpyrazine, formurla is C6H8N2.

The influence of CH … pi interaction on coupling constants across N … H-F hydrogen bond in a substituted T-shaped configuration: a theoretical study
For studying the influence of CH horizontal ellipsis pi interaction on coupling constants across N horizontal ellipsis H-F hydrogen bond in a substituted T-shaped configuration, X-benzene perpendicular to(FH horizontal ellipsis pyrazine horizontal ellipsis HF) complexes are chosen as a working model. NMR calculations are performed at B3LYP/6-311++G(d,p) and PBE0/6-311++G(d,p) levels. Here, correlations between energetic, geometrical and topological parameters and coupling constants are investigated. The results indicate that direct correlations exist between strength of N horizontal ellipsis H hydrogen bond, electron-donating power of substituents and |(2h)J(N-F)|. Also, |(2h)J(N-F)| increases as cooperative and synergistic energies become more negative. These behaviours are reversed for (1h)J(N-H). Due to contradictory behaviours of FC and PSO terms, an irregular trend is observed for (1)J(H-F).
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 123-32-0 help many people in the next few years. HPLC of Formula: C6H8N2.
