The presence of TMPD had no effect on aromatic compounds except for those containing alkyl hydro­ gens. In this case peaks corresponding to (M-H)~ were observed. The most interesting result was for polynuclear aromatic hydrocarbons in the presence of TNB. The aromatic hydrocarbons showed peaks at (M+15)~, similarly to the aromatic nitrocompounds above. An example is the negative ion spectrum of l,2:5,6-dibenzanthracene plus TNB shown in Figure 17. The (M+15)~ peak at m/z 293 is quite distinct. An ion corresponding to (M+NO2)" (m/z = 324) also has been observed for a few of the aromatic hydrocarbons studied.
