The vacuum ultraviolet (VUV) absorption spectra of 2-vinyl furan was investigated. The spectroscopic properties of the 2-vinyl furan was analyzed using electron energy loss spectroscopy and synchrotron radiation source with absolute cross section determinations. The semiempirical molecular orbital calculations was used for the interpretation of the He I photoelectron spectrum. A photoabsorption spectrum was observed in the first band in the UV absorption spectra in solution of furans in position 2 of polyenyl groups of increasing size.
