From: Polycyclic aromatic hydrocarbon formation chemistry in a plasma jet revealed by IR-UV action spectroscopy

Fig. 1

Trace a is recorded with two-color REMPI during our IR-UV ion dip measurements. Products that are assigned to a molecular structure are labeled with their masses in green, see Figs. 2 and 3. Trace b is taken using 118 nm VUV for the region below m/z = 128 and 193 nm UV for the region above m/z = 128. The m/z = 326 would correspond to a formed cyclic structure containing seven aromatic rings.
