Vibrational infrared and raman spectra of dicyanoacetylene
Abstract
The raman and infrared spectra for solid C 4N 2 are reported. New assignments are given for ∼gn 1 (2333 cm -1), ∼gn 2 (2267) and ∼gn 3 (640 cm -1). These assignments are supported by a normal coordinate Analysis using eight force constants. Extinction coefficients for the infrared active fundamentals are also reported. Our results suggest C 4N 2 to be a likely candidate to explain the 478 cm -1 band in the Titan's emission recorded by the Voyager mission.
