science-softCon uv/vis+ spectra data base; www.uv-spectra.de, (C) science-softCon 2018 Substance: 2-chloroanthraquinone Other Names: 2-chloroanthracene-9,10-dione Formula: C14H7ClO2 CAS-No.: 131-09-9 PubChem: CID 8553 Study: UV absorption data (wavelengths of peaks and shoulders are listed) Authors: S.Y. Matsuzaki, A. Kuboyama Title: The two n,pi* transitions of monohalogenanthraquinones Journal/Source: Bull. Chem. Soc. Japan, 51 (8), 2264-2267, (1978); https://doi.org/10.1246/bcsj.51.2264 Data: table, diagram Energy/Wavelength range: 380- 460 nm Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: solution (n-heptane) pH: Comments: The n,pi* absorption and phosphorescence spectra of 1-fluoro-, 2-fluoro, 1-chloro-, 2-chloro-, 1-bromo-, and 2-bromoanthraquinones were studied in solutions, mainly at 77 K. The spectra of 2-F-AQ and 2-Cl-AQ are not displayed. However, these spectra quite resemble the spectrum of 2-Br-AQ. Author to whom correspondence should be addressed: (e-mail address):
