Abstract

Infrared and Raman spectra have been obtained in various physical states for 3,3,4,4-tetrafluorocyclobutene (TFCB) and its singly and doubly deuterated isotopic modifications. Vibrational fundamentals for TFCB are, in cm^-1, (a₁) 3152, 1564, 1350, 1162, 1034, 755, 500, 277; (a₂)-, 957, ∼610, 348, 133; (b₁) 3108, 1338, ∼1150, 1058, 730, 614, 431; (b₂) 1155, 799, 366, 208. Comparably complete assignments of the fundamentals for the d₁ and d₂ isotopomers support these assignments. The ring puckering frequencies of 15 halogen-substituted cyclobutenes are compared. The ring puckering mode at 133 cm^-1 for TFCB fits into the systematic dependence of the frequency of this mode on mass, location and extent of halogen substitution on the cyclobutene framework.
