Description
| - Pi-Pi interakce benzenu a aromatických heterocyklů obsahujících dusík (pyridin, pyrimidin, 1,3,5, triazin, 1,2,3,triazin, 1,2,4,5,tetrazin a 1,2,3,4,5 pentazin) byly studovány pomocí pokročilých kvantově chemických metod. T-struktury všech komlexů vykazují zkrácení C-H vazby doprovázené poměrně velkým modrým posuvem (40-52 cm-1) příslušné C-H vazebné frekvence. (cs)
- The pi-pi interactins between benzene and aromatic nitrogen heterocycles pyridine, pyrimidine, 1,3,5-triazine, 1,2,3-triazine, 1,2,4,5-tetrazine a 1,2,3,4,5-pentazine are systematically investigated. The T-shaped structures of all complexes studied exhibit a contraction of the C-H bond accompanied by a rather large blue shift (40-52 cm-1) of its stretching frequency.
