BIBLIOGRAPHY: A. Fahr and A.K. Nayak, "Temperature dependent ultraviolet absorption cross sections of 1,3-butadiene and butadiyne", Chem. Phys. 189, 725-731 (1994); DOI: 10.1016/0301-0104(94)00306-8
COMMENTS: HC≡CC≡CH

Ultraviolet absorption cross sections and their temperature dependencies were determined employing a one meter, single beam, vacuum monochromator provided with interchangeable vacuum UV and UV photomultipliers, a deuterium light source, an analog to digital circuitry, computer controlled stepping motor for wavelength control and computerized data acquisition system

Absorption cross sections at 5-nm intervals from Table 2
