Low temperature matrix-isolation and solid state vibrational spectra of tetrazole [PDF]

, 2001
Infrared spectra of tetrazole (CN isolated in an argon matrix (T \10 K) and in the solid state (at room 4H2) temperature) were investigated. In the crystalline phase, tetrazole exists in its 1H-tautomeric form and new assignments of the vibrational ...
