Ultraviolet irradiation of the methanoindene compounds chlordene, 1-hydroxychlordene cis-and trans-chlordane, trans-nonachlor and heptachlor using acetone as the sensitizing solvent yielded caged photoisomers. Electron impact spectra of twelve photoproducts are reported. Structural assignments based

β¦ Synopsis
The photodecomposition products of aldrin, dieldrin and endrin were investigated by means of gas chromatography mass spectrometry, nuclear magnetic resonance and infrared spectrophotometry. An alternate isomeric product of aldrin and four endrin analogs were encountered. The mass spectra of eight photoproducts are presented with direct inlet spectra of endrin aldehyde and endrin alcohol.
