Issue Date: | 2020 | Publisher: | SPRINGER | Source: | JOURNAL OF APPLIED SPECTROSCOPY, 87 (3) , p. 421 -428 | Abstract: | The molecular structures and spectral and luminescent properties of 2,3,7,13,17,18-hexamethyl-8,12-di-nbutylcorrole and 7,13-dimethyl-8,12-di-n-butylcorrole free bases in solutions at 288-328 K were studied using luminescence and absorption spectroscopy and quantum chemistry. Absorption and fluorescence spectra of the compounds were shown to be superimposed spectra of two NH-tautomers. Individual tautomer spectra were identified. Bands were assigned to specific transitions. NH-tautomer equilibria in the ground S(0)and lower excited S(1)singlet states were characterized. | Notes: | Kruk, MM (corresponding author), Belarusian State Technol Univ, Minsk 220006, BELARUS. youssef.ajeeb@aul.edu.lb; krukmikalai@yahoo.com; dar.isuct@yandex.ru; wouter.maes@uhasselt.be; llglad@tut.by; m.kruk@belstu.by |
