Unlike the 0-degree case, the
photochemical reaction occurs in the solar radiation zone as shown in Figure 3b and 3c.
We have previously exposed cultured lung cells to similar multipollutant mixtures in the
photochemical reaction chamber and showed that gaseous products elicited biological and biochemical responses in the absence of particles (Sexton et al.

PHOTOCHEMICAL REACTION OF A YE PRECURSOR 4-CHLORO-1,2-PHENYLENEDIAMINE AND ITS ASSOCIATED MUTAGENIC EFFECTS
3,5-Dibromoindene-1-one (6) was generated by radical bromination of 5- bromoindanone (1b) using 2.2 equivalents of N- bromosuccinimid (NBS) in a
photochemical reaction apparatus equipped with a reflux condenser in CCl4 at 77 C (Scheme 1).
For
photochemical reactions the higher concentration causes a higher light absorption and consequently accelerates the degradation rate [26].
(2007) examined the effect of ammonium sulfate aerosol on the
photochemical reactions of toluene (mostly from cars) and nitrogen oxides to form those secondary organic particles.
Subsequently, the prepared compound was irradiated by laser beams (980 nm wavelength) and the
photochemical reaction as well as the liberation of the target species was investigated."
The complexes, 1-9 were prepared by the
photochemical reactions of metal carbonyls M[(CO).sub.6] (M = Cr, Mo, W) with [SB.sup.1], [SB.sup.2], [SB.sup.3] and were obtained in 65 -75% yields by the method given below.
A systematic study of
photochemical reactions started at the dawn of the 19th century and the beginning of the 20th century.
These results demonstrate that some of the [C.sub.60] molecules are bonded to PMMA and form some [C.sub.60]-PMMA adducts by
photochemical reaction during laser irradiation in nitrogen.
