Jet spectroscopy of anthracene and deuterated anthracenes [PDF]
The Journal of Chemical Physics, 1984 Fluorescence excitation and SVL fluorescence spectra of jet-cooled h10-, 9d1-, 9,10d2-, and d10- anthracene are reported. Ground state vibrational assignments are presented for all these species and are compared with literature values. In addition, assignments for the first excited singlet state of h10- anthracene are made using SVL spectra and ...

Photooxidation of Anthracene [PDF]
Bulletin of the Chemical Society of Japan, 1968 Abstract It was found that anthracene (I) was converted to 9,10-anthraquinone (III) and bianthrone (IV) by irradiation via anthracene peroxide (II). The reaction proceeded most effectively in carbon disulfide. Also IV was found to be oxidized to III by oxygen in singlet state.
