✦ Synopsis
The alkyl nitrites, C 2 H 5 0 N 0 , n -C 3 H 7 0 N 0 , n-C4HgON0, and i -C 4 H g O N 0 were photolyzed at 23°C in the presence of "NO at 366-nm incident radiation. The quantum yields of the corresponding isotopically-enriched alkyl nitrites were measured by mass spectrometry. The results indicated that only part of the absorption leads to photodecomposition. The remainder forms an electronically excited state which isotopically exchanges with I5NO. The indicated reactions of the electronically excited state RONO*, are
RONO* -RON0
where k 3 / k 2 = 0.50 t 0.10, 0.62 2 0.20, 0.42 * 0.06, and 0.24 t 0.03 torr, and that k2,/k2 = 1.0, 1.0, 0.64 t 0.04, and 0.56 t 0.03, respectively, for C,HSONO, n-C3H70N0, n-C4H90N0, and i-C,H,ONO.
