Abstract
A Fourier transform infrared isotopic study of the products from the vacuum ultraviolet photolysis of diacetylene and 1,3-butadiene trapped in solid argon has enabled the identification of the 1543.4 cm−1 frequency as a vibration of the C4 molecule. The assignment is confirmed by the observation of the frequencies for seven carbon-13 substituted isotopomers of the molecule.Keywords
