Abstract

ABSORPTION SPECTRUM OF BENZENE IN THE 2000A REGION: Temperature dependence of vibrational transitions in the second electronic transition of benzene was studied. All the vibrational levels observed by Pickett (L. W. Pickett, et al. J. Am. Chem. Soc., 73:4862 (1951)) showed that absorption at a wave length corresponding to the longest wave length transition (from the normal state to an excited level of the second electronic state), with absorption by a constant number of molecules, decreased slightly with increase in temperature because of depopulation of the normal state. At wavelengths longer than the Pickett transition, intensity increases with increase in temperature. LIFETIME OF FLUORESCENCE OF SO2: Transitions in the 3800-5000A region of the emission spectra of SO2 come from the first excited electronic state to vibrational levels of the normal state. ELECTRONIC SPECTRUM OF CARBON SUBOXIDE. A background source for the absorption spectrum was constructed. The vacuum line for preparation and purification of C302 is being assembled.
