Abstract:A careful integration technique has allowed the determination of photodecomposition quantum yields ΦD of 3-chloro-3-methyldiazirine at several wavelengths using conventional equipment. The results obtained are
></figure>A change of collision frequency from 5.0 × 10<sup>7</sup> to 5.7 × 10<sup>10</sup> does not alter the quantum yield which is also unaltered by oxygen. Our data are explained by a mechanism which includes two photodecomposition paths. The first is a direct photodissociation from the electronic state reached by the initial transition and the second involves methylchlorocarbene.</td>
