Abstract
AbstractRaman spectra of 3, 3‐difluoroxetane have been recorded from 50 to 3500 cm−1 in all three physical states. In addition, the infrared spectra of gaseous and solid 3,3‐difluoroxetane have been measured between 200 and 3500 cm−1. A vibrational assignment is presented in terms of the C2ν point group which is based upon the observed band contours, depolarization ratios, group frequency correlations and relative band intensities. Although transitions associated with the ring‐puckering mode of 3,3‐difluoroxetane were not directly observed, a weak absorption at 1228 cm−1 has been assigned to a combination band involving the out‐of‐plane skeletal bending and a CH2 wagging mode. With this assignment, the 1 ← 0 transition of ν24 is estimated to be centered near 69 cm−1. The data reported herein will be compared with other studies on similar ring systems.
