Generalized oscillator strengths, f, for the transition x tBZU 6 % rArg in benzene, determined by electron impact metbods, are reported as a function of the momentum change. At scattering angles down to 2.5" helium wx used as the comparison gas. Determinations are also reported at 0 = 0" using mercu
The t Bzu-t At, fluorescence emission of benzene acited by controlled electron impact was measured in :he !4-100 eV region. The opti-ally forbidden 6 ' levels xvere prefcrentiaUy acited. This indicates rhnr 3 non-dlpolr: rranution rakes place under low-energy electron-molecule collisions.
N2B3ng, Y = O-2 and N\*a"v;, Y = 0 were produced by pulsed rodiolysis af nitrogen (100-2000 torr) and fo!lowed by fast kinetic absorption spectroscopy in the second and fifth positive system. T!le rate constants for the denctivation of the species by nitrogen were found to be ~N~A,~ = 1.6i + 0.8; 2.
The laser-induced fluorescence (LIF) spectrum of the B 3 ⌸ 0 ϩ u -X 1 ⌺ g ϩ system of Br 2 was recorded by Fourier transform spectroscopy (FTS). The LIF spectra were obtained by using continuous-wave dye laser excitation in the spectral region 16 800 -18 000 cm Ϫ1 . About 1800 rotationally resolved
