This annotated bibliography of the analytical chemistry of 2A,6-Trinitrotoluene, alternately referred to as a-TNT or TNT, covers a period ranging from ca 1940 to the present. Over this period, the field of analytical chemistry and, therefore, that of TNT has advanced from the simple wet chemical to the automated, computerized and highly complex instrumental methods. Because of this wide spectrum of advancements, the analytical chemistry of TNT will be formated according to the general categories of ... 

Fig. 3. The v+ region of the nuclear quadrupole resonance (NQR) spectrum of mixed orthorhombic and monoclinic 2,4,6-trinitrotoluene (TNT). The positions of the orthorhombic and monoclinic resonances at 13°C are indicated by O and M , respectively (data from Fig. 3 of reference [91]).

Fig. 2. The infrared absorption spectrum of vapor above solid mil-spec 2,4,6-trinitrotoluene (TNT) at 340 K. The spectrum is identical to that measured above solid DNT at the same temperature (measured by the authors).

Fig. 12. The ultraviolet absorption spectrum of 2,4,6-trinitrotoluene, reproduced with permission from [93]. The solid line is the spectrum of gas-phase TNT measured at 92 °C the dotted line is the spectrum of the TNT ethanol solution measured in reference 10 of [93]. Arrows labeled as 1, 2, and 3 show die peaks corresponding to NO A 2%+(v = 0, 1, 2) X 2II(v = 0) absorption transitions, respectively.

The Sq->S2 absorption spectrum of nitrosobenzene in a supersonic jet has been measured indirectly by monitoring yields of photoeliminated NO." Photolysis of the furoxan (63) (Scheme 5) generates two molecules of NO and the acetylene (64)." At 17%, the yield is low, but this is the first example of the photoelimination of NO from a furoxan to have been reported. A method for detecting nitrobenzene has been developed in which laser photolysis is combined with laser-induced fluorescence of the resulting NO fragments." A similar approach to detecting 2,4,6-trinitrotoluene in soil and groundwater has also been described." ...

Three ion peaks are seen in this mobility spectrum. The first, at a drift time of about 6 ms, is called the reactant ion peak (RIP) and is present in the spectrum even when a sample is not. The next two ion peaks are ion peaks of 4,6-dinitro-o-cresol, a common contaminant from smoke, with a reduced mobility of 1.59 V cm s and 2,4,6-trinitrotoluene (TNT) with a reduced mobility of 1.54 V cm s. For...

Mmiaturized Ion Mobility Spectrometry, Fig. 2 Ion mobility spectrum of 100 ng trinitrotoluene as analyzed by Itemiser (GE-Interlogix), a commercial ion mobility spectrometer. Two peaks were observed, the chloride reactant ion peak (RIP) and the trinitrotoluene (TNT) peak. The TNT peak had a drift time of 5.35 ms, with a peak width of 0.34 ms...

It is of interest that the visible spectrum of the Meisenheimer compound does not resemble the visible spectrum of either the product of reaction of s-trinitrobenzene with an alkoxide ion or the product resulting from the interaction of s-trinitrotoluene with an alkoxide ion. Moreover, these last two spectra do not resemble one another. The s-trinitrotoluene-alkoxide product has a spectrum similar to picrate ion. It shows a maximum at 370 m/t whereas picrate ion shows one...
