Vibrational spectrum and internal rotation in 3-METHYLPYRIDAZINE (cas 1632-76-4)

Add time:07/25/2019    Source:sciencedirect.com

In this work the Raman spectrum of 3-methylpyridazine is reported for the first time and the infrared spectrum has been remeasured. On the basis of the experimental data a general assignment is proposed which is consistent with a Cs symmetry. The molecular structure as well as the potential energy barrier for the internal rotation of the methyl group and the theoretical spectrum for that rotation has been computed in the MINDO/3 approximation level.
