Abstract
The mass spectra of 1,2,3‐benzotriazole and some derivatives with substituents at the 1‐position and in the benzenering have been examined. The loss of N2from the molecularion is characteristic; loss of N2 plus the 1‐substituent is also common. Structures are proposed for these fragment ions. The relative ease of loss of N2, NO and NS from the molecular ions of benzotriazole, 2,1,3‐benzodiazole, 1,2,3‐ and 2,1,3‐benzothiadiazoles is compared.Keywords
