用时间分辨红外光谱法研究了2，6-二氟苯基叠氮的液相光化学。在243 ~ 283 K之间，在1404 cm（-1）处观察到2，6-二氟苯基氮烯（1 N）的单重态振动带。在环境温度下，不可能检测到该中间体。在298 K时，只有单线态氮烯的衰变产物，即异构化产物烯酮亚胺（K）和三线态-2，6-二氟苯基氮烯（3 N）分别在1576和1444 cm（-1）处被观测到。分配是一致的密度泛函理论计算和以前的研究，该系统的激光闪光光解技术与紫外-可见光检测。
The solution-phase photochemistry of 2,6-difluorophenyl azide was studied by time-resolved infrared (TRIR) spectroscopy. A vibrational band of singlet 2,6-difluorophenyl nitrene (1N) was observed at 1404 cm(-1) between 243 and 283 K. At ambient temperature, it was not possible to detect this intermediate. At 298 K, only the decay products of the singlet nitrene, the isomerized products ketenimine (K) and triplet-2,6-difluorophenyl nitrene (3N), were observed at 1576 and 1444 cm(-1), respectively. The assignments are consistent with density functional theory calculations and previous studies of this system by laser flash photolysis techniques with UV-visible detection.
