Vibrational Spectra and Assignments for 3,3,4,4-Tetrafluorocyclobutene-d0, -d1, and -d2
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.
