Abstract: | A nanosecond laser spectrometer consisting of a 3nsec ruby/Nd PTM laser, fast detection system and high brightness analysing source is described. An analysis of the geometry considerations is given for crossed beam and collinear arrangement. The excited-state absorption spectra of naphthalene in 3MP at 85°K and 293°K from 14000 to 30000 cm?1 are given. The results provide a direct method to evaluate the quantum yields for fluorescence φf and intersystem crossing φT. Also the excited-state absorption spectra of anthracene in PMM from 16000 to 26000 cm?1 and in 3MP from 26000 to 36000 cm?1 are reported. |
