Abstract
The ν3 fundamental of diazomethane. which essentially corresponds to a symmetric methylene deformation has been reinvestigated at a resolution of 0.07 cm-1 . The J- and Ka-structures of this A-type band have been resolved and analysed for the first time. The rovibrational assignment is given and, using Watson's S-reduced Hamiltonian, the rotational and quartic centrifugal distortion constants could be determined for the first excited vibrational state of the symmetric methylene deformation.Keywords
