Application
1,2-二氟苯 (1,2-DFB) 被用于研究邻-、间-和对-二氟苯离子的离解机制。它和 x 射线光电子能谱和程序升温脱附一起用来研究 1,2-DFB、1,2-二氯苯和 1,2-二溴苯在 Si (100) 2 x 1 上的室温吸附。。它还被用作转换金属配合物电化学研究的溶剂 。
用于过渡金属络合物的电化学研究的溶剂。

Threshold photoelectron photoion coincidence (TPEPICO) experiments have shown that o-, m-, and p-difluorobenzene ions dissociate via a common, ring-opened intermediate and not via ionized p-difluorobenzene. Rice-Ramsperger-Kassel-Marcus (RRKM) modeling of the experimental breakdown curves yields activation energies for the initial isomerization

Electronic noses have been widely used in the food industry to monitor process performance and quality control, but use in wastewater and biosolids treatment has not been fully explored. Therefore, we examined the feasibility of an electronic nose to discriminate
