The T-T spectra, the triplei quantum yield $IJ-and the fluorescence quantum yield QF of 2-tert butyI+methylindazole and 1,3dimethylindazole have been measured in the temperature range of +25" to -L96"C in solucnts of different viscosities. It could be shown that in all c;ises where photochemical rea

β¦ Synopsis
Collisional quenching rates with helium as a collision partner have been obtained for selectively excited rovibronic levels of the A 'Di state ofCO+ at T= 94.207 and 298 K. Data are reported for collision induced electronic transitions with various energy gaps and Franc!c-Condon factors. The rate constants are approximately two to three orders of magnitude larger

Electronically excited CH was produced by multiphoton dissociation of acetone at 248 nm. Measurements of the electronic relaxation of specific rotational levels of CH( A 'A) by acetone show that the quenching efficiency decreases as N' is increased, in accordance with room temperature results on OH\
