a Experimental setup to study the interaction of N2 with water vapor plasma at ambient conditions. Stainless-steel discharge needle was used as electrode. DC: direct current. The figure is adapted with permission from refs. 18,20,21. b The corresponding mass spectrum of ionic products in Fig. 1a. Asterisks correspond to the products specific to the reaction between water vapor plasma and N2. c Ion trap reactor applied to study the reaction between N2 and isolated (H2O)2+• (m/z 36) in vacuum. The figure is adapted with permission from refs. 18,20,21. d The corresponding mass spectrum of ionic products in c. Asterisks correspond to the products specific to the reaction between water vapor plasma and N2. e Ionic fragments of the reaction intermediate at m/z 64 induced by collisional activation inside the ion trap. f Mass spectrum of the ionic species observed during the interaction between water vapor plasma and 15N2 (15N2 gas instead of 14N2 in a). Asterisks correspond to the products specific to the reaction between water vapor plasma and 15N2.
