The electronic spectra of bipy-and bipyz-anions (bipy = 2, P'-bipyridine) have been measured between 5000 and 50 000 cnl-1. The observed bands which have intensities betweenf = 6.30 x lo-2 and f = 0.52 are assised on the basis of HMO and Parker-Parr calculations. It is well known that 2,2'-bypiridi

The fluoresccncc from ten vibronic states in the 2300 to 2100 A absorption region of SO2 has been studied. A sharp drop in fluorescence quantum yield and fluorescence lifetime for wavelengths shorter than 2206 A is a:t:ibuted to the dissociation of SO,. 'Ihe quantum yield of fluorescence in the spec
Excitation of the B 3tTu+u state of 12 in CC& solution with ~8 ps fwhm 531 nm mode-locked pulses yields substantial fluorescence, which contrasts with the pure resonance Raman emission spectrum displayed under 5 14.5 nm cw argon ion laser pumping.
With 1,2-benzanthracene and fluoranthene population of higher excited singlet states S,, (n > 1) by triplet-triple1 annihilation is energetically possible. With both compounds a delayed fluorescence Sn + So from the highest accessible singlet state St1 was found (n = 3 for 1,2-benzanthracene and n =
