摘要: The vibrational spectra of the crystalline s‐tetrazines show several infrared and one Raman band which have split into two Davydov components. These results are in agreement with predictions correlation table. However, magnitude splittings cannot be successfully explained by either dipole–dipole or intermolecular hydrogen repulsion potentials. coupling mechanism is probably due to an interaction between π cloud molecule ring atoms its neighbors.
