## Abstract The difference between the tripletβtriplet and singletβsinglet absorption spectrum of naphthalene has been measured at 90Β°K using a newly developed computer controlled spectrograph. Good spectral resolution has been obtained and a strong band was found in the ultraviolet region. Recent

In this note we report the polarization of the well known triplet-trip@ absorption of anthracene in the 4500 -4100 A region and the assignment for the total space symmetry of the upper state. The short lifetime of the anthracene lowest triplet state makes this determination slightly more difficult t
The polarization of the triplet-triplet (T-T) absorption spectrum of a-, p-hydroxynaphathalene and 2,3-dihydroxynaphthalene from 4000 to 6000 A wz~s measured. The obtained data were compared with theoretical ulcu~tions on T-T absorption spectra and polarization data on the lowest-energy singlet-sing
Tne triplet-triplet absorption spectrum and its polarization of picene were measured from 3750 to 15 800 A. &sides the strong transition at about 6300 A, two others are located at 4875 and 9300 A. These experimental data were compared with calculated results obtiined by Orloff The triplet-triplet
