The photographs of the near ultraviolet absorption and fluorescence spectra excited by Hg 3650 A and 2537 A of anthracene, phenanthrene and chrysene were taken at temperatures between room temperature and liquid hydrogen temperature. They were analysed by using the sharpening and separation of bands, and several progressions of the totally symmetrical frequencies superposed by the nontotally symmetrical ones were observed. Besides such general feature of spectrum as above, the lattice vibration may be taken in the fluorescence spectra of anthracene and chrysene ; the anomalous change in the position of intensity maximum in some fluorescence bands of anthracene was discovered at temperatures between -196° and -253℃.
