Triazolate complexes spectra

The IR and Raman spectra of benzotriazole, benzotriazole anion and its Cu(I) complex have been measured. The characteristic peaks in the IR spectrum of the triazole moiety in benzotriazole anion occur at 1163 cm , 1134 cm , and 1115 cm . A broad band with a main peak at 1151 cm occurs in the spectrum of the Cu(I)-BTA complex <85JST(l00)57i>. The chemisorption of benzotriazole on clean copper and cuprous oxide surfaces is investigated by combining XPS, UV-PE and IR reflection absorption spectroscopy (IRAS). Coordination geometry including the triazole-... 

Benzoyl- and 4-butyryl-triazoles form iron complexes when treated with iron(II) chloride in THF under nitrogen. A Mossbauer spectrum was measured with this complex <66DOK( 170)354). Similarly, Fe2(CO)9 reacts instantly with the above 4-aroyltriazoles to give... 

In vivo detection of NO is commonly accomplished using the fluorophore4,5-diaminofluorescien (DAF-2). When the fluorophore reacts with N2O3 (a species related to NO), it is converted to a triazole derivative, DAF-2T. Dehydroascorbic acid present in cells also reacts with DAF-2 and forms a complex with an emission spectrum similar to that of DAF-2T, thereby interfering with NO detection. The separation of the interfering speeies with CE-LIF has allowed quantification of NO in single cells, along with ascorbic acid and dehydroascorbic acid, which both play important roles in cellular metabolism.
