✦ Synopsis
CIN$ (N=C-C=C-C=N+
) is produced in a self-igniting dc discharge from the neutral precursor seeded in neon and matrixisolated at 5.5 K. From Fourier-transform absorption, laser excitation and emission spectra of the cation's A *IIs * X *lIU transition the three symmetric C, vibrational modes were obtained for both states involved and are compared with the corresponding gas-phase values. Additional emission bands are assighed to combination and overtone bands involving the asymmetric stretches and two bending vibrations of the ground state. Subsidiary emission/absorption bands are interpreted as the forbidden ALL f 1 transitions which become allowed due to perturbations by the surrounding matrix.
