Notes:
Measurements of the D(R—NO) bond strength in some C-nitrosocompounds have been made using an electron impact method. The appearance potential of the radical ion (R+) has been determined, the D(R—NO) bond energy being obtained from the relation \documentclass{article}\pagestyle{empty}\begin{document}$$D{\rm (R} - {\rm NO) = }AP{\rm (R}^{\rm + } {\rm)} - IP({\rm R}.)$$\end{document} The values obtained are: D(C6H5—NO) = 41 kcal/mole, D(t-C4H9—NO) = 34 kcal/mole, D(t-C5H11—NO) = 36 kcal/mole and D(i-C3H7—NO) = 36.5 kcal/mole. These values are in good agreement with the numerous estimations of Benson and coworkers and confirm that the C—N bond strength in C-nitrosocompounds is very much less than in nitrocompounds or in amines.
