The vibronic sequences shown by the SI+So spectrum of biphenylene have been calculated by means of the relevant vibronic coupling and Franck-Condon factors. The results of our calculations make it possible to identify the bzu modes and a, modes responsible for the spectrum and involved in the radiat

β¦ Synopsis
The spcclficlty of fluorometry IS u\cful m the qualitative analysis of a compound without prior szpsration. EIowevcr. in some CBSCS. the fluorcsccncc emission due to two compctmg Processes may take place at clo~ly xparatcd wavcIengths. It 15 suggested that in such d ca5c. the polarlzdtlon spectrum may bc used to distmguish bchvccn processes giving overlapping fluorcsccncc bands. * Pcrmancnt address. Dcpartmcnt of Physxs. hI.hl.

The polarization of the excimer fluorescence from the dinucleotide CpC has been observed to be strikingIy different from that of the monomer. The mixed polarization in the absorption reflects significant ground state interaction. The mixed polarization in the fluorescence is most likely due to a com
Fluorescence polarization experiments on molecules dissolved in ordered liquid crys+als are described. It has been found that the monomer and excimer emissions of pyrene are perpenciicuLarLy polarized.
The polarized luminescence spectrum of single crystals of Zn3Eu2(N0,)12.24Hz0, measured at 77 K under laser-selective excitation, is presented. The spectra are interpreted by using Cp, symmetry, and are afterwards related to the crystallographic determined C, model at the site of the hexanitrate. Th
