COMMENTS: N≡CC≡CC≡N

Extrapolation of the measured (323, 293, 263, and 233 K) absorption cross sections of ten maxima to a temperature of 170 K (Titan's high atmosphere)

Absorption coefficients in cm-1 amagat-1 from Table II (base e) have been converted to absorption cross sections (conversion factor 3.72×10-20)
