The remarkable versatility of triazenes in synthesis, polymer chemistry and pharmacology has led to numerous experimental and theoretical studies. Surprisingly, only very little is known about the most fundamental triazene: the parent molecule with the chemical formula N 3 H 3 . Here we observe molecular, isolated N 3 H 3 in the gas phase after it sublimes from energetically processed ammonia and nitrogen films. Combining theoretical studies with our novel detection scheme of photoionization‐driven reflectron time‐of‐flight mass spectroscopy we can obtain information on the isomers of triazene formed in the films. Using isotopically labeled starting material, we can additionally gain insight in the formation pathways of the isomers of N 3 H 3 under investigation and identify the isomers formed as triazene (H 2 NNNH) and possibly triimide (HNHNNH).
