Chemistry of the NH-N Fraction

Schulten et al. [16] identified the following N-containing compounds in NH-N fractions separated from several soils by pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) pyrrole (la), methyl pyrrole (lb), pyridine (IVa), methylpyridine (IVb), indole (Via), and benzothiazole (XI). The Roman numerals refer to the chem- 

Pyrolysis-field ionization mass spectrometry (Py-FIMS) and Curie-point pyrolysis-gas chromatography/mass spectrometry (CpPy-CC/MS) of soils 

Aside from the N-compounds listed above, a number of low-molecular-weight N compounds were also identified. [17] These included ammonia, hydrogen cyanide, dinitrogen (N2), nitric oxide (NO), methylamine, nitrous oxide (N20), formamide, acetamide, and N, N-dimethylmethanamine.
