Cyanogen, NCCN

Cyanogen, NCCN, is a colorless, violently flammable gas with a pungent odor. It may cause permanent injury or even death in exposed individuals. Fumes produced by the reaction of cyanogen with water or acids are highly toxic. 

NCCN Photolysis. Cyanogen (NCCN) photodissociation has also been considered a prototypical statistical dissociation reaction. After absorption to the 11,, 1 Au manifolds, the dissociation is thought to proceed via internal conversion to the ground-state surface. Previous studies have measured the rotational state distribution of the CN fragments from photolysis of cyanogen at 193.3 nm [75-77], The threshold photon energy for CN formation was found to be 47,000 200 cm -1 [78].

Richardson and Nixon (1968) have measured the relative infrared and Raman intensities of the lattice modes of cyanogen (NCCN), a linear molecule. The six infrared active modes are all translational motions and the quadrupole-induced intensities were calculated using the theory of Schnepp (1967) adapted for a different crystal structure. It was found that the experimental intensities of individual lines could be fitted to the theory within factors of two to three by adjusting the sample thickness, i.e., one parameter. However, if suras of intensities for each symmetry type are compared, to separate the intensity problem from the lattice dynamics problem, much better agreement is obtained, well within a factor of two. The relative Raman intensities of the librational lattice modes were also found to give good agreement between theory and experiment.

We have considered here only the case of a a orbital because, in general for diatomic molecules, excitation to a nominal n orbital lies in the discrete part of the spectrum. Examples of 7T shape resonances have been observed in polyatomic molecules as, for example, the cyanogen molecule, NCCN (see Lynch et al., 1986). 

Cyanogen is slowly hydrolyzed by water, in part giving (11-XIV), which indicates that the order of atoms must be NCCN. This is fully confirmed by structural studies, which show the molecule to be symmetrical and linear... 

Cyanogen is a linear molecule with the structure NCCN. List the number of electrons in MOs of each symmetry representation in the ground state of this molecule. For example, for H2O, there are six dj electrons, two bi electrons, and two electrons. Don t worry about the order of the energies.
